Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensurin…

How A Magnetic Power Generator Works. Basically, a magnet generator is powered by magnets. Magnets set on opposing poles will deflect each other. With this premise, if magnets were to be placed in an inner circular wheel, with another group of magnets facing them on an outer wheel, they would be deflecting each other indefinitely.
