magnetic levitation

noun

1. the suspension of an object above or below a second object by means of magnetic repulsion or attraction.

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.

magnetic levitation

1. 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).

Magnetic levitation (or maglev) trains are capable of cruising speeds of up to three hundred miles per hour.

Example Sentences
