Simple magnet circuit

  1. Sep 3, 2011 #1
    Hello everyone,

    as you may notice I am new to this forum. Unfortunately I've been stuck on a small problem for a few days and I can't seem to find the solution.

    It appears to be a simple problem so I am hoping that someone here, with a bit more electrical engineering background as myself might be able to help out.

    I have a permanent magnet in an L-shape (take B = 0.5 Tesla in order to avoid saturation), with the n-pole on the one end and the s-pole on the other. The idea now is to make this into a square circuit by moving a conducting metal into the gap.

    My question here is: How can I derive the attraction force which is acted on the metal by the magnet from the gapsize between them.

    The dimensions are still unknown but I just need help with the formula's. Been looking at Coulomb's and Maxwell's for too long without seeing the solution. Any help would be thankfull.
