What is Magnetic levitation?
[[File:Science show magnetic levitation.jpg|thumb|Magnetic levitation can be achieved using different techniques, here rotation is used]] '''Magnetic levitation''', '''maglev''', or '''magnetic suspension''' is a method by which an object is [[levitation|suspended]] with no support other than [[magnetic field]]s. [[Lorentz force|Magnetic force]] is used to counteract the effects of the [[gravitational acceleration]] and any other accelerations. The two primary issues 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 neutralized. The sizes of magnets also has a role in the levitation. While using smaller magnets it is easier to control levitation and experimental conditions. Magnetic levitation is used for [[maglev train]]s, [[Induction heating|contactless melting]], [[magnetic bearing]]s and for product display purposes. {{stub}} [[Category:Magnetism]] [[Category:Technology]]
