Magnetic levitation or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. The two primary features involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralised. Magnetic levitation is used for maglev trains, contact-less melting, magnetic bearings and for product display purposes.
