Distance over Force of a Magnet

  1. Mar 7, 2012 #1
    A experiment was conducted where we had an electromagnet and a magnet. Our aim was to see how close the electromagnetic would need to be before it would attract/repel the other magnet. We recorded the distance between the two magnets and the difference in mass of the normal magnet. The force was then calculated and then plotted against distance.
    See attachment for results

    Theoretically, the trend of distance against magnet strength should be an inverse squared function however our results are showing an inverse cubed function? Any ideas?

    Thanks :)
