WebWhere is that energy coming from? I've been told that this machine could not be perpetual due to the fact that magnets lose their magnetism over time. While this is true, I don't find this explanation satisfying, because if … WebMar 13, 2024 · You basically answered your own question, though - it isn't possible because causing the fan to spin with a static magnet would violate conservation of energy. The main problem is that if you get it spinning, each magnet spends some time attracted to the one in your hand and some time repelled from it. On average, it cancels out.
