The Makin' of a Maglev




The big difference between a maglev train and a conventional train is that maglev trains do not have an engine. The magnetic field created by the electrified coils in the guide way, walls, and the track combine to propel the train.
The basic idea of how the Maglev train works is by Electromagnetic Repulsion. The train floats along the guide way or track. A magnetized coil along the track repels the magnet along the belly of the train allowing it to float. Once the train is levitated, power is supplied to the coils within the guide way walls to create a unique system of magnetic fields that pull and push the train along the guide way. The electric current supplied to the coils in the guide way walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.

The lack of friction on the train allows the train to get up to speeds of 310 mph which is twice as fast as Amtrak.

The train is propelled along the track as fast as the magnets work their magic both pushing and pullin or attracting and repelling which keeps the train moving as well as suspended in the air for good mobility with little friction. With the perfect synchrony of the magnettic systems the train can tracel on its own circuit.
