Making use of the force of permanent magnets has been a curious human pastime ever since the discovery of naturally occurring Lodestones 2,500 years ago.
The availability of modern super strong Neodymium magnets and fertile imaginations has led to many unusual motors powered by permanent magnets alone, requiring no fuel or external energy to work. Who knew an iron marble could be the future of power generation!?
Presented for your viewing pleasure is the most dazzling and almost hypnotic example of magnetic motion, and other creative ways of applying magnetic effects. Sit back, relax and hit the play button to begin relearning everything you thought you knew about magnets and engines.
Many of these devices are touted as perpetual motion machines, they are not. The magnets providing the fields will lose their power over time, until the engine stops and they need to be replaced. Still recycling a magnet is a simple enough task and these types of systems have the potential to generate small amounts of power over long periods of time without stopping or refueling.
