I havnt taken physics in a while and cannot remember much. But i came here to see if an idea i had was possible. The idea is that if you were to spin a magnet in space(becasue from what i remember if you spin an object in space it continues non-stop(i have bad memory though)) you can use the spinning magnet like a hydro generator, to create limitless electrical energy. But first i want to know if you were to spin a magnet in space if(pt1) it will continue to spin non-stop and (pt2) it could be used like a hydro generator were it has coils around it to create electricity. Please answer this if possible.
