I heard of several materials that are canidates for magnets and lose little or no current in doing so. I later wondered if switching the magnetism of a superconductive magnet on and off in a closed circuit instead of a chemical blast could be used to power something. Just like a car engine, instead of adding fuel to a car, why not control magnetism to push on the piston just like a chemical explosion does on a typical car.
