  2. Railroads. the suspension of a vehicle above or below a suitable guide rail by such means, often with the vehicle being propelled by a linear induction motor.

A process by which a magnet moving over a piece of metal causes electric currents (see also current) to flow in the metal that, in turn, produce forces that push the magnet upward. If the force is large enough, the moving magnet can float (be levitated).
