Question of the Week / QotW - 07.12.09 - Power Source for Magnets?
« on: 06/12/2007 13:51:09 »
From where do permanent magnets get their energy or power? I can put a fridge magnet on a fridge, and it seems as if it will stay there forever with no sign of any power source. Also, if I try to push the like poles of two bar magnets together, my arms will grow tired long before the magnets grow weak, yet again there is no power or energy source. Can we not harness this invisible and seemingly endless source of energy?
