Title How does the size of the magnet affect it's strength?
Introduction/Purpose Ben: Today in our lab investigation, we tested whether the size of the magnet affects it's magnetic pull. Our hypothesis was that the size of the magnet affected it's pull. WHAT AFFECT DID YOU THINK IT WOULD HAVE?
Methods Brooke: The following materials that were needed to complete this lab were three magnets, (small, medium, large) paperclips, and a ruler. These are the steps that we followed. First, we started the paperclip at zero cm, and a magnet at ten cm. Then, we moved that magnet closer to the paperclip. Next, we watched until the paperclip reached the magnet. Last, we recorded how many centimeters until the paperclip reached the magnet. Try to be detailed enough that anybody would be able to copy your method.
Results As shown in the following graph the size of the magnet did not make a difference it was the material of the magnet that makes a difference in its strength.(Anthony) How did you know it was the material? What about the magnets that were made of the same materials? Did size matter?
Interpretation Nick: Our hypothesis was not supported, because we thought the bigger the magnet the stronger the pull because of mass. We were wrong. The data shows that our hypothesis is wrong because the greatest distance the biggest magnet pulled was 2 cm, but the greatest distance the smallest magnet pulled was 3 cm thus proving us wrong. Our data adds to the idea that even if one magnet is bigger than the other, the smaller one could have a greater magnetic pull.
Additional Discussion All: One difficulty we encountered was how fast the magnet was moved each time. Compared to the other groups, our data was different because we had different magnets. If we were to do this lab again, we would test each size more than three times, and we would make sure the speed is the same each time we move the magnet closer to the paperclip. These are all good points.
