Whenever you stroke a magnet against a plate of copper or another good conductor of electricity you always get a force that opposes the movement of a magnet called and eddy current. What i want to know is can you calculate the repeling force of the eddy current? and if so how? I know that the key to the equation must have something to do with the strength of a magnet, how well the conductor conducts and the relative motion of the magnet or copper plate.
Thanks!
