JHAQ Posted October 9, 2004 Share Posted October 9, 2004 Natural magnets exert a force which is capable of doing work . It takes energy to to do work . In magnets what is the source of this energy when it is not electromagnetically induced ? I know the theories of magnetism but nowhere can I find what the energy source is --- is it nuclear ( ie by conversion of mass ) at some level ?
