Title: Magnetic Forces and FieldSubtitle: Lab 23Lab Partners: Amber TelscherDate: 1/02/16Abstract:This lab consisted of two experiments, both dealing with magnets. The first experiment dealt with magnetbehavior and dealt with observing the behavior of the ceramic ring magnets when compared to one another in various ways. This was mainly to have us see what would happen if you compared North to North and South to South, and also the result when you brought the South Pole to North Pole. For the second experiment, it demonstrated magnetic field lines of a magnet by using a compass by following the direction of the arrow within the compass in comparison to the stationary magnet. Lastly, we are able to see the magnetic field lines of the magnet bar by sprinkling iron filings on a piece of paper hovering over a magnet in order to see how the filings are attracted to the magnetic poles when exposed to the field. Thetake home message for the second experiment is that magnetic fields originate from the North Pole and terminate to the South Pole.Introduction and Background:This lab is exclusively designed to map, learn, and visualize magnetic field lines when conducting a laboratory designed to explore Magnetic Forces and Fields. The hypothesis for this lab is that the magnetic field lines will flow from the North “pole” and around to the South “pole” to complete a whole magnetic field loop around the magnets used for the experiment. Method:There were two experiments to this lab; Experiment 1 regarded magnet behavior and Experiment 2 regarded magnetic field lines. Both of the experiments were useful to help better understand magnets and how magnetic field lines actually flow through a magnet consisting of both a North and a South pole, regardless if the magnet is split in half. Both of the labs were conducted on the flat surface of a table. The control in this experiment would have to be the use of the same magnets throughout. The variable in this lab would have to be the orientation on the magnets and the combination in which they were being tested. The materials required for this lab included, four ceramic ring magnets, iron filings, a compass, masking tape, a permanent marker, and a sturdy sheet of paper between both of the experiments.The first experiment included of labeling the sides of two ceramic ring magnets and completing a series of comparison with the magnets to see how they interacted with each other. This part of the lab in particular consisted of comparing two magnets, magnet A and magnet B, and then seeing how they interacted with each other when each of the sides were brought close to one another. The results found forthis part of the lab will be included in the results section of this report. The next part of the first experiment included stacking all four magnets together to make a larger magnet bar and proceeded to investigate the effects of how the magnets interacted with each other, especially when taking off magnet Aand recording the results when comparing how the magnets were either attracted or repelled against each other and how they acted when brought close to one another and to the fridge. The second experiment involved Magnetic Field Lines, and helped us observe magnetic field lines of a combined magnet bar that had four ceramic ring magnets and demonstrated this by sprinkling iron filings on top of a sturdy piece of paper hovering the combined magnet bar to show the actual magnetic field lines that are occurring from the magnet. This lab had us sketch out the magnetic field lines, not only of the magnet with the iron filings, but also simply with the use of a compass to help us visualize which way the magnetic field lines are moving by monitoring the direction of the compass arrow as it orbited around the stationary magnets.Results:The major findings from the first experiment were that the magnets when added together had a stronger effect on each other than when there was only one magnet having an effect on an object. Another notable result from Experiment 1, was that opposite poles attracted one another and like poles repulsed one another. For the second experiment, one of the most notable results found during experimentation is that magnetic field lines flow exiting the North pole of a magnet and they flow/loop around the present magnet until they enter back into the magnetic field entering from the south pole section of the magnet or magnetic barconsisting of four ceramic ring magnets combined together to form one stronger magnet bar. The photograph of the magnetic filings demonstrate how the magnetic field lines flowed while they were poured on top of a piece of paper hovering over a vertical magnetic bar. One notable thing from the picture is that you can see the direction of the arrow in the compass and it is pointing away from the magnet, however, it does not show the full effect of the compass circling around the magnet to show the magnetic field lines. Even though you cannot see from the picture how the magnetic field lines are demonstrated from the compass, you can still visualize the field lines from being exposed to the magnet below the piece of paper.Discussion:This entire lab was designated to help us better visualize magnet behavior and the flow of magnetic field lines from a magnet. The results of the experiment support my hypothesis that magnetic field lines indeed flow from the North pole of a magnet and wrap around to the South pole of the magnet and this was shown in this lab by the use of the compass and iron filings. For the very first lab some notable observations from placing the magnets together, were that there was a much stronger attraction and repulsion among magnets when they were all together making a stronger magnetic field. Another thing I noticed during the magnetic behavior lab was that there seemed to have been a pole change once the A magnet was removed from the stack of magnets and was exposed to the refrigerator. The reason I say this is because A2 was attracted to the metal surface and then once it was brought back to the stack, there was an attraction as well. Perhaps there was a swap in poles when the magnet was exposed to the fridge, which led to an opposite result than I would have expected from this part of the lab. In regards to my results comparing to the industry standards, I am sure that my experiment would not pass the industrystandards due to the fact that they put in many more measures to show
