Next, stick a small piece of tape on (or otherwise mark) the longer piece of the cut nail, near the cut end. This is so you will be able to tell the two ends apart after cutting. Have your instructor cut the longer piece of your magnetized nail according to your directions, and then test the ends of the two pieces with your compass as before. Do these results suggest that the head piece is one-ended, two-ended, or something else? What about the middle piece? Both are two-ended. Mark the four ‘ends’ in the diagram below according to whether each was a N-pole, S-pole, or no pole. S N S N Check with some other groups. Do their observations seem to suggest that the results of both experiments you did in this exploration depend on exactly where the magnetized nail was cut, or are every group’s results the same? Summarizing Questions S1. When a magnetized nail is cut into pieces, is each piece one-ended, two-ended, or something different, or does the result depend on exactly where the nail is cut? What evidence supports your answer? When a nail is cut into pieces, each p...
