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.
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.
' Shanghai Maglev Demonstration Operation Line ') is a magnetic levitation train (maglev) line that operates in Shanghai, China. The line uses the German Transrapid technology. [ 2 ] The Shanghai maglev is the world's first commercial high-speed maglev and has a maximum cruising speed of 300 km/h (186 mph). [ 3 ]
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 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).
The increased scrutiny of container traffic has, however, pushed them to find alternative Channel crossings, which helps explain the sharp rise in Vietnamese people using small boats. 'Success ...
The California–Nevada Interstate Maglev project was a proposed 269 mi (433 km) Maglev train line from Las Vegas, Nevada, to Anaheim, California. One segment would run from Las Vegas to Primm, Nevada, with proposed service to the Las Vegas area's forthcoming Ivanpah Valley Airport. The top speed would be 310 mph (500 km/h). [2]
