[1] Given 2 permanent magnets, a magnaprobe, and a meter stick, develop a method for comparing the strengths of the poles of the two different magnets. That is, be able to figure out which magnet has stronger poles.
[2] Using the method that you developed in part [1] above, determine which of your three types of magnets has the strongest poles. Determine also which has the weakest poles.
[3] Now come up with a quantitative definition for the strength of the pole of a magnet. Quantitative means that this definition should allow you to assign a number to each pole, and that this number should represent the pole's strength. Your definition should be an operational one - that is, you need to give me sufficient information so that I could use your method and come up with the same strengths that you did.
