magnetic levitation, maglev(noun)
high-speed rail technology; train is suspended on a magnetic cushion above a magnetized track and so travels free of friction
a method of supporting and transporting objects and vehicles by using a magnetic field to counterbalance the gravitational pull
Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic pressure is used to counteract the effects of the gravitational and any other accelerations. Earnshaw's theorem proves that using only ferromagnetic or paramagnetic materials it is impossible to stably levitate against gravity, but servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents permit this to occur. 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.
