Assume the following situation: Two magnets are isolated from two charges. The two magnetic poles are close to each other and the two electric charges are close to each other. What evidence is there that the potential energy stored in the fields of both the magnets and the charges will convert to kinetic energy directly?

a)Both the magnets and the charges will become warmer the closer they are to each other.

b)Both the magnets and the charges will start to move, either away from each other or towards one another.

c) Both the magnets and the charges will experience a change in fields due to their presence to each other.

d)Both the magnets and the charges will not experience a net force from each other.
