Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
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.
Maglev has the advantages of being quieter and smoother than wheeled transportation due to eliminating much of the physical contact between wheels and track. Since a maglev requires a guiding rail, it is mostly used in railed transport systems like trains.
The institute maintains a website filled with data, charts, maps, photos and videos of several types of maglev technology being developed around the world. [6] NAMTI resources are used by transportation planners, engineering firms, and governments around the world considering new maglev transport projects.
On Earth, a mass-driver design could possibly use well-tested maglev components. To launch a space vehicle with humans on board, a mass driver's track would need to be almost 1000 kilometres long if providing almost all the velocity to Low Earth Orbit , though a lesser length could still provide major launch assist.
Magnetic river is an electrodynamic magnetic levitation (maglev) system designed by Fredrick Eastham and Eric Laithwaite in 1974. It consists of a thin conductive plate on an AC linear induction motor. Due to the transverse flux and the geometry, this gives it lift, stability and propulsion as well as being relatively [vague] efficient. The ...
