Hi,
I have two questions about permanent magnets:
1. How do you calculate the work done by a permanent magnet on, say, an iron plate?
2. I am aware that the force exerted on an object by a magnet depends on the surface area. Is it also affected by the thickness of the object to a certain extent? What is the minimum thickness after which thickness is not an issue?
Thanks.
