magnetic levitation definition


A process by which a magnet moving over a piece of metal causes electric currents 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).

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