Hello, Steponit, Yes, there's something missing here, alright. Please Register or Log in to view the hidden image! The part about a magnet having energy. That's simply not correct. And the only way to extract energy from a magnetic system is to first add energy to it - such as passing a wire so that it cuts the lines of flux. And it's the motion of moving the wire that is adding the energy. A magnet is simply a magnet. It contains no more or no less energy than another piece of iron or steel that isn't magnetized.
