Set Up: Place an Air track on table and make sure to level it using something like notecards. Make sure there are magnets on the end supports of the air track and also on the glider. The vacuum will provide a force through the holes in the track and keep the glider afloat so we can oppose any drag due to the glider touching the track.
Procedure:
1) Because we have no set equation for magnetic potential energy we must build our own for it. We will use the relationship of potential energy being equal to the negative integral of force over distance.
2) If we raise one end of the air track the glider will slide and find an equilibrium point at which the magnetic repulsion is equal to the parallel gravitational component.
3) We stacked different heights of books underneath one end of the track and measured the distance between the glider and the opposing magnet and also recorded each new angle due to the raising of one end.

4) To plot this data in logger pro we first had to convert the angle measures into radians so that we could calculate each force using trig functions in logger pro.
5) Once we graphed each force vs the separation distance we used a power fit(Ar^B) to calculate a coefficient and exponent to be able to later integrate.
6) Now that logger pro has given us our A and B we can find the negative inegral of the force over distance to calculate an equation for magnetic potential energy.
