2 - Assignment Example The in-depth interviews involved a word association exercise with the informants. A diagram that shows the concepts that students relate to marketing was developed, based on the results of in-depth interviews, indicating the most frequently occurring connections. A detailed explanation of what was learnt about how college students view marketing was provided. As indicated earlier, the informants comprised of four college students who are not business majors. The main aim was to find out the perceptions of these students on marketing. The following questions were asked during the in-depth interviews and the informants were allowed to provide their responses in detail: The first informant defined marketing as the act of advertising and promotion of products or services. The second informant claimed that he understood marketing as an effort that is carried out to create brand awareness. The third informant linked marketing to consumer research, whereby she said that all marketing personnel should possess the ability to find out about the needs of consumers so that they can sell appropriate products and services to them. The fourth respondent defined marketing as manipulation of a consumerââ¬â¢s beliefs to enhance selling. According to the four informants, marketing involves various activities. For instance, one informant said that promotion, which is majorly carried out through advertising was the main activity of marketing. Another respondent perceived pricing and retail decision making as a major activity of marketing. Creation of brand awareness by marketing personnel was perceived as one of the main activities of marketing by one of the respondents. On the other hand, one of the informants claimed that the main activity of market research, which enables marketers to create a brand by carrying out quality research on how consumers perceive a product, service or organization. This research involves the identification of clientsââ¬â¢ needs, and

Compare and Contrast Essay Example for Free
Compare and Contrast Essay Religion is a great topic to develop and more when you compare and contrast them. Everyone has different views based on their belief. In this essay Im going to compare two basic religions that are still use in todayââ¬â¢s society after so many years of development. These religions are buddhism and christianity. Considered to be the two great distinctive religions of the world, both Buddhism Christianity today covers a large section of the world population with numerous similarities and differences. There are huge differences on this religions that outstand all the others. The existence of a personal creator and Lord is denied by Buddhism. However, Christianity believes in a personal creator and each may have a relationship with the creator, Jesus. Buddhism believes the world operates under natural law and power and Christians believe that there is a divine order to the world. Some in Buddhism deify the Buddha and worship other gods as well. Christianity is clear that a personal God exists but He is to be the only object of worship. Buddist believe that through a blowing out of yourself, freeing you from desire, will you break the cycle of reincarnation. Christianity says that a relationship with God through belief in the sacrificial work of Jesus Christ on the cross is what allows people to go to heaven. This only comes when someone completely trusts in what God has done for us in the person of Jesus Christ. There is no such thing in Buddhism as sin against a supreme being. In Christianity sin is ultimately against God and affects man and this world. According to Buddhist belief, the human life is not consider to have much worth, having only temporary existence. Life is understood in such a way in getting rid of all desire (good and bad) and not placing any value on this life on earth and not to believe there is any eternal soul to a person. In Christianity people are of infinite worth, made in the image of God, and will exist eternally. The human body is a hindrance to the Buddhist while to the Christian it is an instrument for glorifying God as well as God will restore the body of those who commit their lives to him so that they can be in his presence forever. Also there are some things in which Buddhism and Christianity are really similar. Lord Buddha based His ethics on the golden rule, which was for the welfare of the human beings. Christianity, Jesus Christ also preached His ethics as per the golden rule, which was for the welfare of His people and easily approachable. Buddha, the founder of Buddhism rejected extreme asceticism and gave an emphasis on self-liberation through knowledge. On the other hand Jesus Christ also rejected extreme asceticism. The worship in Buddhism includes monasticism, ringing of bells, bowing, use of incense and rosary, erection of towers or stupas, prayers and meditation. Similarly, the Christians also follow almost same form of worship Monasticism, Confession, the cult of images, ringing of bells, use of rosary and incense and the erection of towers. The Buddhist doctrine gives an emphasis on love for the entire mankind and every other beings as well, no matter whether the being is a friend or an enemy!. The Christian doctrine is also based on the principle of Love the neighbour like into yourself, which means that love should be showered upon not only your friends, but the entire beings. In conclusion buddhism and christianity like any other religion have their similarities and their own differences.

Futures and Options Essay
Futures and Options Essay The agreement to buy and sell such commodities is made through contracts to bring in legality in trading as it involves cash payments margins, delivery of goods and scope for profit maximisation. The emergence of contract systems eventually led to trading in contracts whereby a middlemen stands in between buyers and sellers. The active trading in such contracts brought standardisation which in turn led to the development of futures contracts. A future contract is a standardised, binding agreement to make or take delivery of a specified quantity and grade of a commodity at an established point in future at an agreed upon price. The organization of merchants involved in the trading these commodities evolved into an organisation that standardised the contracts and trading practises and came to be known as The Futures Exchange such as the New York Board of Trade (NYBOT) and the London International Financial Futures Exchange. One essential objective of the exchange is to provide the dealers with all necessary information with regard to price volatility i.e. the magnitude of price movement in either direction. Note that it measures price risk and volatility but does not remove or eliminate risks. The exchange provides the benchmark for the determination of price by making price margins mandatory for effective fair trading. Future transactions do not require full advance payments for the commodity (just the margin), the buyer of a futures contract which increases in value (or the seller of futures contract which decreases in value) can realize a profit which can be substantial in relation to the commitment of capital. Brazil today is the world largest producer of coffee. Considering this figures, it is not surprising to note that it has attracted considerable amount of speculation and ever increasing susceptibility to price volatility. Coffee production has direct linkage with weather besides many other factors such as world coffee prices. A coffee drink manufacturer will buy coffee beans from a coffee producer at an agreed price if he/she expects to have drastic climatic changes which will result in coffee being expensive at a future date. A sudden drop in the production in future will cut supply and make it more expensive. the buyer can, therefore, avoid unnecessary risk by buying a futures contract that will guarantee him delivery of coffee at a future date at a price fixed now. However, it must also be noted that he/she will suffer loss if the future current/spot price of coffee beans were to fall drastically due to improved production and competitions. Take an example of Brazil The Brazilian Crop was initially expected to produce about 50 million bags of coffee. Seasonal disturbances such as rain, harvest delays and quality problem caused production to fall to 33.5 million bags. Due to severe drought in Viet Nam coffee production dropped by almost 1 million bags. These shortages of coffee output distort the supply level which leads to a global rise in prices. So what roles does the future markets play in the production and selling of coffee? Taking these points into account the next chapter looks at the Indian and world coffee markets and the role future market plays in its pricing. In the analysis, I have made use of some articles from the Times of India newspaper and other websites. It is logical to state that at times of shortage prices tend to go up due to higher demand and which in turn puts pressure on sellers to sell their product at a lower price. We know from our analysis before that a buyer will resort to futures contract if he expects the prices to go up in future. However considering that the production too has been low the chances of producing the required amount to meet the demand is less which adds to speculation in the market. The report also suggests one source as saying that it is better to pay penalty and cancel a contract rather than to loose significant amount of money by fulfilling it. Note that sometimes the whole idea of futures contract is not meet the obligation in terms of delivering the commodity but to profit from the speculation that these uncertainties give rise to. The world coffee production in 2003/2004 was estimated to be around 105.3 million 60 kilogram bags down nearly 2 percent from forecast made in June and down 15 percent from the 2002/03 season. Factors such as lower production contribute to great extent the price determination. For the year 2004/2005 it was widely believed that Brazilian coffee production to be around 33-35 million bags but due to substandard weather and low level of investment the production is likely to be below 30 million bags. This drop in production is likely to cut the supply level and Brazil being the world largest producers, any drop in its output will affect the world supply and thereby raise the price. These uncertainties lead to prices going up in the futures markets. It has long been felt that some traders hold stocks to push the prices up and then sell it to make supernatural profits. Lets look at the graphical representation of prices of Robusta class of coffee as determined at the International Coffee Organisation (ICO) to assess the trends in the market. The graph below shows that since November 2004 Robusta coffee prices have increased at a slow and steady pace. However, a report that appeared on the Economic Times suggests that volatility in the world prices over the last few days have affected trading in coffee in the markets. The ICO in its Coffee Market Report seems to suggest that the downturn in mid-April caused a slight fall of 3.19 percent in the monthly average of the ICO Composite Indicator Price which dropped from 101.44 cents/lb in March to98.20 cents/lb in April. It also suggests that this has been due to high level of activity from various investment funds. Comparing the results put forward by the ICO to the recent reports in the Economic Times newspaper (24/05/2005) the volatility in the world prices have triggered a bullish trend in the Indian markets which explains why trading in the coffee auctions markets have suffered. Estimates shows that there was a 40 percent drop in the overall quantum sold when compared to the previous ICTA auction. The beginning of the year showed a significant climb in the moving averages between January and mid-March and then a significant drop till the mid of April. One of the least complex ways to use a moving average is to simply look at the slope a rising slope indicates that the market is in an uptrend and falling slope indicates a downward trend in the market. Moving Averages is a statistical technique for smoothing price movement in order to identify the trends more easily. It is equally important to understand that moving averages are sensitive to the number of days used to calculate the average i.e. the more days that are used; the less sensitive is the average. Some experts are of the view that MA can be a critical factor in decision making. For e.g. traders can make use of one or more MA to determine buy or sell decisions i.e.to use a slow MA together with a fast MA. A slow moving average can be calculated by taking more days opening or closing prices and fast moving average by taking fewer days prices. In a more elaborate way, what it means is that you must buy when the faster MA goes above the slower one and sell when the faster MA goes below the slower one [or] buy when prices are above both fast and slow MA and sell when prices are below both MA. The chart below is a graphical example of how a Moving Average looks like as of 05/27/2005. The Red Line (price line) is above the moving average so the trend is up indicating that the market is bullish and also the fast moving average (dark blue) is above the slow moving average (light blue). Volume of7078.00 suggests the measure of trading activity during the selected period of time. It refers to the number of futures contract that are either bought or sold during that period. Open Interests, on the other hand, measures the number of futures contract that remains open at a particular point in time, usually at the closing of trade. In the next chapter, I have looked at India as a producer of Coffee. India is relatively new into the coffee future markets and has performed exceedingly well. However, due to the speculative nature of the futures market and also bureaucratic hurdles have led to decrease in contract sales and increased price and non-competitiveness in the global coffee market. The two principal species of coffee grown in India are Robusta and Arabica. Trading in coffee futures was introduced only recently and prices are extensively depended on the coffee trading in the New York and London futures markets as it has considerable influence on the world coffee prices. These prices are notoriously volatile and varies considerably due to factors such as weather forecast, size of the coffee stock worldwide and speculations in the futures markets The Indian coffee production and physical trade is worth over $ 430 million annually. The production of Indian coffee is greatly influenced by world prices particularly since it is the second largest actively traded commodity in the world market. The Coffee Futures Exchange India Limited was formed under the supervision of Forwards Markets Commission to look into all trading practices affecting coffee prices. The main objectives are To provide hedging opportunity against coffee price risk. To ensure guaranteed delivery of coffee. To provide a price discovery mechanism for future period up to 18 months at any given point of time. Besides these it is important to look at the mechanism COFEI uses to ensure that market participants follows the rules in ensure financial integrity. Factors such as margins, Price limits for trading, daily marking-to-market of all trades and sufficient capital including guarantee funds ensures that proper procedures are followed when a contract is bought and sold. In India, coffee has been categorized into 4 different types with each having different margins for smooth and efficient trading. The table next page gives a snapshot view of how coffee in India is traded and in particular the different class of coffee whether raw or clean. The coffee industry, in general, has seen surge in prices by almost 40 percent. Exports in recent times have been hit quiet badly. Reports on the Financial Express newspaper suggest that export have suffered especially due to the price non-competitiveness in the world markets. India exported nearly 225,000 tonnes of coffee last year with majority (50 %) of it going to Europe. Indias coffee production and exports for the year 2005-06 (October-September) are forecast to increase by 5% and 29%, respectively. The anticipated rise in coffee export is against the backdrop of almost 26% decline in the current year (2004-05/Oct-Sep). Coffee exports are expected to fall to an eight-year low of 169,980 tonne, or 2.83 million 60-kilogram bags, in the current year ending Sept 30, from 229,320 tonne, or 3.82 million bags, a year earlier. India, the worlds fifth-biggest coffee exporter is set to witness decline as farmers and traders are withholding beans on expectations of higher prices. One of the biggest problems facing the traders in the Indian coffee industry is the time difference between India and the New York and London trading centres. Indian traders were now finding it difficult to hedge their risk. The local exchange functioned only till 5pm when the LIFFE and NYBOT and other European markets functioned till over 11.30 pm IST.

Sophoclesââ¬â¢ Oedipus Cycle â⬠Antigone, as a Feminist Essay -- Antigone E
Sophoclesââ¬â¢ Oedipus Cycle ââ¬â Antigone, as a Feminist Throughout history, women have always stood in the shadows of men. In many cultures, the role of women has always been to be seen and not heard. As one of the first feminists in world literature, the character Antigone, of Sophoclesââ¬â¢ Oedipus Cycle, displays fine characteristics of a great female leader in order to stand up against male dominance for her religious, political, and personal beliefs. When the king denies her brother, Polynices, proper burial, Antigone goes against state law by burying him herself in order to protect heavenly decree and maintain justice. In doing this, she steps out of her place as a woman in a male dominated society. In order to characterize Antigone as a feminist, it is important to study Antigoneââ¬â¢s early childhood, which displays the origins of the characteristics found in her that make her a feminist. In Oedipus of Colonus, Sophocles illustrates these qualities that Antigone possesses. During the first twenty years of her life, Antigone spends her time secluded from society with her blind, exiled father, Oedipus. Sophocles sums up her childhood in the following soliloquy by Oedipus: "Since her childhood ended and her body gained its power, has wandered ever with me, an old manââ¬â¢s governess; often in the wild forest without shoes, and hungry, beaten by many rains tired by the sun; yet she rejected the sweet life of home so that her father should have sustenance" (Fitts 104). Because she is secluded, Antigone never has to take her place in society as a woman. Without a female role model to show her how a woman is supposed to act, there is no one to raise her as a woman. She spends her days taking care of her blind father and leading him. Sh... ...Creon, when she kills herself causing Creon to lose. Creon at this point has caved in by deciding to bury Polynices and free Antigone, but it is too late. She dies an honorable death for future feminists. Since Sophocles wrote Antigone, there have been thousands of literary works about feminists and their movement to let their voices be heard over men. Through her strong will and bravery, Antigone made her political, religious, and personal beliefs seen. She died in order to win against men even when no one else would stand up to male dominance. For these reasons, Antigone is a prime example of a great feminist in world literature. Works Cited Fitts, Dudley and Robert Fitzgerald. The Oedipus Cycle. Trans. Sophocles.

A Case of identity Essay
Through a comparison of ââ¬ËA Case of identityââ¬â¢ and ââ¬ËThe Stolen Cigar caseââ¬â¢ discuss how successful Bret Harte is in parodying Sir Arthur Conan Doyle.à There are two forms of detective story: there is the ââ¬Ëwho dunnitââ¬â¢ idea in which gentlemen detectives are called upon in all sorts of impossible situations, but always manage to solve the crime. In this type, the reader has a good idea of who committed the ââ¬Ëcrimeââ¬â¢; however, the characters in the story donââ¬â¢t. The other type of story is a mystery, in which neither reader nor investigators know who is responsible for the crime; together with the characters, the reader too is invited to figure out the sequence of events. In the Sherlock Holmes stories the focus is on the character of the detective himself (Sherlock Holmes) and follows the story of him solving a mystery. Sherlock Holmes (S.H) was a legendary figure as he was the very first fictional detective; his stories were written in the Victorian times by the writer Sir Arthur Conan Doyle.à The S.H stories have many common features. For example S.H is seen to be very well organised and by the end, his efforts have concluded in solving the mystery/crime. This has made it easier for Bret Harte to parody Conan Doyleââ¬â¢s style; he uses many similar features like the same old fashioned language and also in having Sherlock Holmes or Hemlock Jones (as he is called in the parody), portrayed as a very precise, eccentric detective. In the original story, we are told of how Miss Mary Sunderland goes to S.H to find Mr Hosmer Angel-her missing bridegroom-who disappeared on the day of their wedding. S.H manages to find this man, so uncovering the fact that it is her step-father in disguise!à In the parody; ââ¬ËThe Stolen Cigar Caseââ¬â¢, Hemlock Jones (H.J) accuses Watson of stealing his cigar case and constructs an elaborate/exaggerated story to prove his point, only to find he had misplaced it! In ââ¬ËA Case of Identityââ¬â¢ Watson is the narrator, who, as he is some what naà ¯Ã ¿Ã ½ve, has to have things explained to him; this assists the reader. He tries to work out S.Hââ¬â¢s process of deduction, often unsuccessfully, so S.H explains in a straightforward manner through Watson to the reader. He takes the role of the pupil and is a necessary link between Sherlock and the reader. As we look at things from Watsonââ¬â¢s point of view we are able to see how S.H unravels the cases and solves the crimes. S.H is admired greatly by Watson; likewise readers also come to admire him as an exponent of ratiocination. Throughout the story, the impression is given that S.Hââ¬â¢s previous clients have all been people high up in society as he had ââ¬Å"a little souvenir from the king of Bohemiaâ⬠in return for Sherlock helping him with a case. He has many valuable belongings, many of which have been gifts from wealthy clients of his such as his ââ¬Å"snuff-box of goldâ⬠.à He also refers to similar cases to the ones he is working on ââ¬Å"You will find parallel cases, if you consult my index, in Andover in ââ¬â¢77â⬠. This also shows that he is an experienced detective with a powerful memory and someone in whom one can have faith.

Brick and Mortat vs. Online Shopping Essay
Everyone has to shop one day for something. Individuals have the option to shop in the store or online, but it will depend on the personââ¬â¢s to how he/ she would like to purchase products. Article One from CNN I Report by More Life March 2009 Bricks and Mortar vs. Online Shopping Article Two from Ezine Article by Gary Palmer 2012 Comparing Online to Brick and Mortar Shopping There are times that a person is unable to physically go to a store to buy items. The convenience of shopping at home benefits both the consumer and the company. The company would not suffer in profit, if a customer is unable to leave home or is stuck at work. Providing customers with the option online keeps the customer shopping and the stores profiting. Provide customers with easy payment options online and at a brick-and-mortar, shop offers shoppers the flexibility to shop. No matter if you shop from home or in the store, you have the option of a using credit, debit cards, or a check for payment. There are not many people who carry cash, so having this option is a great convenience. Convenience and flexibility in shopping is the key to a happy customer. Now days, individuals can purchase medicine and food online. There are many mail-order pharmacies that will fill and re-fill prescriptions and mail to the patientââ¬â¢s home. Surprisingly, there are online grocery stores, such as Peapod and Swans, where shoppers can choose their items online and have their groceries shipped to the house. Most grocers will charge a fee to delivery, but this is another convenience. The problem with this is that the company may lose out on the extra profit made, because an actual shopper in the store will browse the store and pick up extra items. Brick-and-Mortar shopping allows consumers to feel, touch, and try on items before purchasing. According to the article by CNN ââ¬Å"I Reportâ⬠, mentions how the shopping has shifted from shopping for cars online. The bad part of the situation is that you cannot feel or touch the item before buying. The article also talks about return policies. If a shopper buys an item and it does not fit or is not the right color, the individual ends up being put out because h e/she needs to ship something back, may have to spend more to ship and items back, and loses valuable timeà returning items that were not quite, what he/she expected. Return policies have flaws depending on if it is mail-order or in the store purchase. Purchasing something in the store allows for on-demand return, money back or store credit. You can even exchange for another item or a different size. Returning in the mail, could lead to some headaches with the return. Repacking, sometimes paying a return fee and getting to a shipper, then waiting on the reimbursement can be a little time consuming. In both ways of shopping, items can be returned, but for a price, whether it money or time. Overall the internet is there for the convenience of people. According to the article, ââ¬Å"Palmer 20120â⬠mentions talks about low overhead and there no need to use display space or storage cost. The bricks to Mortar stores, there are all type expenses from lighting, heating and air conditioning and gas usage. Also, there are maintenance and warehousing cost, to cut out shrinkage, where the bricks to mortar do not have that worry. The online tend to specialize in hard to find items not just only regular items. The retailers for brick to mortar can only house local on-demand items. Online stores can go from national markets to international markets for hard to find items. The convenience shopping online it is in the comfort of your home or wherever you can get the internet service. Once you complete your shopping, your shipping order can go to your home, office or wherever your requested it to be delivered. There are times that you might have to pay for shipping and other times the shipping is free, depending on the special discount that might be going on that companies use to lore people to their website. I personally love online shopping for myself because there are times that I cannot find what I want in the store. Shopping online gives me the opportunity to look and compare different items all at once. Also there are stores that only carry certain sizes online. Recently, coupons have become more popular online. According to the Consumer Report survey, Warehouses store online shopping for example BJ Samââ¬â¢s and Costco Clubs. Membership they are not free rewards member who spend a $100 capped purchases, there are over 1000 locations. Check their return policies; BJ has 30 days where Costco return policies 90 days where Sam Clubs, 100 % guarantee in merchandise. Sam Clubs and Costco has the same return, polices, where BJ is for less liberal. Coupon BJ accept only where manufacturers coupon BJ has 24 hours feature sale online promotion deals.à Sam Clubs discount are deeper with online auctions for members only y bids starting at 1.00. The bottom line shopping at warehouse it down to the individual preference. According to the survey, the big box stores are top ranking is Costco by a narrow margin. In conclusion, when times are challenging with schedules, there still a distinct advantage held by the brick and mortar store, but the gap closing. Many people have lost their jobs due to the internet and advance technology. Household budgets are lower due to the economy, so buyers look for deals with online shopping and it is always open. Some people prefer not to shop online due to the security of their information.

Factors affecting the strength of an electromagnet Essay Example
Factors affecting the strength of an electromagnet Essay Example Factors affecting the strength of an electromagnet Essay Factors affecting the strength of an electromagnet Essay Introduction: An electromagnet consists of a long coil of wire wound on a soft iron core. When current flows through the wire the soft iron core becomes magnetized by induction and thus acts as a magnet till the current flows. The strength of an electromagnet can be affected by various factors such as no.of coils, specific resistance of the wire used to coil the core, the thickness of the wire etc. In this experiment the effect of changing the no.of coils and the thickness of the wire used will be determined.Aim: To determine the effect of changing the no.of coils and the thickness of wire used on the strength of an electromagnet.Hypothesis:* The strength of a magnet will increase with increase in no.of coils as more current passes the iron core causing more efficient magnetic induction and thus a stronger magnetic field.* The strength of the magnet will increase with the increase in the thickness of the wire too because it is already known that resistance is inversely proportional t o cross-sectional area. Thus as resistance drops, more current will flow through the electromagnet causing a larger magnetic field.Apparatus: Soft iron core ( a long nail) Copper wire of three thicknesses Power supply Metre rule Connecting wires and alligator clips A magnetic compass AmmeterProcedure:1. Take 80cm of a chosen thickness of copper wire.2. Tightly wind it around the soft iron core 40 times. 40 coils should be on the core.3. Leave a little wire towards the ends for connections to be made.4. Set up the circuit as shown:5. Align the electromagnet created north with the help of a compass.6. Now place a metre rule parallel to the electromagnet so that the distance from the electromagnet at which the compass deflects may be recorded.7. Now switch on the power supply and adjust the current flowing to 0.5amps using the controls on the power supply.8. Let the current flow for about thirty seconds.9. Then, place the compass, aligned north, on the edge of the metre rule at 100cm a nd slowly slide it along the meter rule towards the electromagnet.10. As it slides, keep a close eye at the distance at which the compass first shows deflection and record the distance observed.11. Now reduce the no.of coils to 35 and cut the extra wire keeping only a little at the ends to make connections.12. Keep reducing the no.of coils to 30, 25, 20, 15, 10 and recording the distance at which deflection occurs.13. Follow the same procedure with different thicknesses of wire.A modification in procedure:== It is known that soft iron magnetizes quickly because its domains are aligned quickly, thus there was a break given between the experiments and the iron bar hammered once gently to remove as much magnetism as possible before carrying on with different no.of coils and thickness.Safe Test:== The un-insulated wire should not be touched when current is flowing.== The current should be kept at a safe level and a current overload indicator must be attached to the circuit.== The circui t should not be left un-monitored and the power should be switched off as soon as the work is done.Fair Test:== The current was kept constant for all the different thicknesses of wire and different no.of coils.== The material of the wires, copper, was also constant.== The voltage applied was also kept constant.== The compass used was the same for the whole experiment.== The length by which the wire was cut every time the no,of coils was reduced was also kept constant.== The electromagnet was realigned every time its position was moved to changed the no of coils.Observation:Raw Data TableTable 1: Table showing the variation in distance at which the compass deflects with change in no.of coils and diameter of the wire.No. of CoilsDistance at which compass deflectsDiameter of copper wire0.26mm0.58mm0.97mm1019.023.026.51521.525.029.02025.528.031.02528.031.034.03032.035.037.03536.038.041.04039.042.046.0The only raw data that may be processed is the diameter of the wire to find the cross-s ectional area of the wire.Processed Data TableTable 2: Table showing the variation in distance at which the compass deflects with change in no.of coils and cross-sectional area of the wire.No. of CoilsDistance at which compass deflectsCross-sectional area of wire of copper wire0.05mmà ¯Ã ¿Ã ½0.26 mmà ¯Ã ¿Ã ½0.74 mmà ¯Ã ¿Ã ½1019.023.026.51521.525.029.02025.528.031.02528.031.034.03032.035.037.03536.038.041.04039.042.046.0Graph 1: Graph showing the change in extent of electromagnetic field with the change in no. of coils on the electromagnet.Graphical Analysis: The graph above clearly shows the positive correlation between the no of coils and the distance at which the compass deflects. As the no.of coils are increased, the electromagnetic field of the magnet increases steadily. Also, a distinct difference and similarity is seen between the graphs of the different thicknesses. Their gradients are very similar, even though the position of the graph changes with each thickness. T he effect of thickness will be depicted further in the next graph. A few points that are off the lines of best fit are not entirely anomalies but, probably, the result of not enough results of other inaccuracies which will be discussed later.Graph 2: Graph showing the changes in extent of magnetic field with the changing thickness of wire.Graphical Analysis: This graph clearly shows the variation in extent of magnetic field at every thickness for the different no.of coils. The difference in the values of different thicknesses is quite noticeable and also constant.Conclusion: After close observation and analysis, it can be concluded that as the no.of coils on an electromagnet increase, so does the extent of the field created by it. Also, as the thickness of the wire used for coiling increases the resistance of the wire drops and the electromagnet becomes stronger. The hypothesis stated earlier has been proved right.Evaluation: Overall, this experiment proved to be quite successful ap art from the minor inaccuracies in readings. However, this experiment could have been made better:== The experiment could have been carried out more times for a better average.== The effect of a larger range of varying thicknesses could have been determined.== Two compasses could have been used for measuring the distance at which deflection occurs to take the average distance of both of them.== The effect of changing the material of the wire could have also been seen.
