Short Background

Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. The electromagnetic force is used to counteract the effects of the gravitational force.

In some cases the lifting force is provided by magnetic levitation, but there is a mechanical support bearing little load that provides stability. This is termed pseudo-levitation.

Magnetic levitation is used for maglev trains, magnetic bearings and for product display purposes.

MAGLEV, or magnetic levitation, is a system of transportation that suspends, guides and (usually) propels vehicles, predominantly trains, using magnetic forces. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems. The technology has the potential to exceed 4000 mph (6437 km/h) if deployed in an evacuated tunnel.

The highest recorded speed of a maglev train is 581 km/h (361 mph), achieved in Japan in 2003, 6 km/h faster than the conventional TGV speed record.
