No, no, no! Magnetism doesn't work that way. It's a conservative force, like gravity. You can get power by letting something fall downhil, but you have to put in the energy first to get it up the hill. Same with a magnet. You can get energy by letting the magnet pull something towards it, but you have to put in the same amount of energy to pull it away. No free lunch, IOW :-)
