Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
Alternating magnetic fields, even purely alternating attractive fields, [18] can induce stability and confine a trajectory through a magnetic field to give a levitation effect. This is used in particle accelerators to confine and lift charged particles, and has been proposed for maglev trains as well.
The super-speed Transrapid maglev system has no wheels, no axles, no gear transmissions, no steel rails, and no overhead electrical pantographs.The maglev vehicles do not roll on wheels; rather, they hover above the track guideway, using the attractive magnetic force between two linear arrays of electromagnetic coils—one side of the coil on the vehicle, the other side in the track guideway ...
Old Dominion University maglev: In 1999, Old Dominion University agreed to work with American Maglev of Atlanta to construct an on-campus student transportation link of less than 1-mile (1.6 km) — using a smart train / dumb track design in which most sensors, magnets, and computation were located on the train rather than the track.

In EDS maglev trains, both the rail and the train exert a magnetic field, and the train is levitated by the repulsive force between these magnetic fields. The magnetic field in the train is produced by either superconducting magnets (as in SCMaglev) or by an array of permanent magnets (as in Inductrack). The repulsive force in the track is ...
An electrodynamic wheel is a type of wheel proposed for use in electrodynamic levitation of the maglev train transport system. [1] [2] [3]Unlike a conventional wheel, an electrodynamic wheel has a rim studded with magnets of alternating poles.
L0 Series maglev train at Yamanashi test track. The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research Institute.
The National Maglev Initiative (NMI) was a research program undertaken in the early 1990s by the United States Department of Transportation, U.S. Army Corps of Engineers, Department of Energy, and other agencies which studied magnetically levitated, or "maglev", train technology, operating at speeds around 300 miles per hour (480 km/h).
