You say " If it doesn't move it doesn't perform work or have power". Lets say you have a scale with a hanging basket. You put a permanent magnet in the basket, then put a 10 # weight of iron UNDER the basket and it stays there defieing gravity. The scale shows it is holding up 10#. Even though nothing is moving,there is a force that is holding it up there. And God only knows how long it may stay there. If you held that same weight up at arms length, even though you didn't move it, you would get tired pretty soon. Right? So I still say a permanent magnet has a power or force of it's own. That power comes from the atoms of the material(matter in motion) according to E= MC squared.
