This Magnetic Levitator is a fascinating near-perpetual motion device that levitates by a magnetic field. Its axle floats by repelling magnets and there is only one small friction point where the metal tip touches the glass. Because of the small friction, the levitator can rotate for a surprising amount of time. Principles of physics can be demonstrated in any science classroom through this great levitator!
