An Introduction to Magnetic Levitation:
Magnetic Levitation (mg´lev) or maglev, support and propulsion of objects or
vehicles by the use of magnets. The magnets provide support without contact or friction, allowing for fast, quiet operation.
In a typical system, the vehicle, which resembles a railroad car, travels above a guideway. Arrays of magnets of like polarity
in both the vehicle and guideway repel each other, producing the lifting force. By continuously changing the polarity in alternate
magnets, a series of magnetic attractions and repulsions is created that moves the vehicle along the track. The electrical
energy required for such a system is great and the use of superconducting materials offers the only realistic potential for
this means of transportation. Research into such systems has been conducted since the 1960s in the United States,
Great Britain, Japan,
and Germany. Maglev technology was applied in England
in the construction of a fully automated, low-speed shuttle in Birmingham, but
the line was closed because of maintenance problems. In 1996 funding was approved in Germany
for a maglev train linking Berlin and Hamburg,
but it was canceled in 2000. In 2002 a maglev line linking Shanghai's financial district with its new airport was opened,
with scheduled operation projected for 2004; called the Translev, it can reach speeds of 267 mph (460 kph) along its 18.6
mi (30 km) route..
