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.
Since a maglev requires a guiding rail, it is mostly used in railed transport systems like trains. Since the first commercial maglev train was opened in Birmingham , England in 1984, other commercial EMS maglev train systems, such as the M-Bahn and the Transrapid have also been put into limited use.
The vactrain proper was invented by Robert H. Goddard as a freshman at Worcester Polytechnic Institute in the United States in 1904. [3] Goddard subsequently refined the idea in a 1906 short story called "The High-Speed Bet" which was summarized and published in a Scientific American editorial in 1909 called "The Limit of Rapid Transit".
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.
In animals, the mechanism for magnetoreception is still under investigation. Two main hypotheses are currently being discussed: one proposing a quantum compass based on a radical pair mechanism, [2] the other postulating a more conventional iron-based magnetic compass with magnetite particles.
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).
Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was an English electrical engineer, known as the "Father of Maglev" [1] for his development of the linear induction motor and maglev rail system after Hermann Kemper's theories and after Charles Wheatstone's pioneering.
