Permanent magnet simulation
 

Hello. I want to simulate a motion of permanent magnet with iron plate. There is a iron plate and permanent magnet under the plate. There is a magnetic force between plate and magnet. I want to move the permanent magnet on x-axis and I want to see the motion of iron plate depending on movement of the magnet. How can i simulate this? I am waiting for your helpful answers. Please do not answer like this : You can not do that! :)
