How does Maglev works?

Question

Hey people...
I wanted to know...i know that maglev trains run on the basis of magnetism...but how....does the magleve train move forward?
give a detail description...that would be nice if you all could help me...i know the basic concept and have seen and read how it works...but need a more detailed descriptuion on how the whole magnetism works....plz explain in simple terms.

Answer 1

The cars are lifted by the magnets in the track, in "repel" mode! Then as each magnet in front of the car is energized, the rear magnet is shut off, and the "pull" of the front magnet pulls the car forward!
The raise and lower magnets are separate from the pulling magnets!
As the car moves forward, faster on-off mode of the pulling magnets makes the car speed up.
To slow down, the change speed of the magnets is slowed, too, allowing the car to slow down and stop.
Being that i'm not an electrical engineer, nor a Maglev expert, the preceding is just a layman's way of explaining how it works!
Try an experiment: Using a flat magnet, and another flat magnet, try to put one magnet onto the other one. If you have them placed with the pull upward, and try to place the other flat magnet onto the lower one, they will either repel each other or stick together! If they don't stick together, and you can move one around, you have discovered the Maglev idea and how it works!

Answer 2

They are lifted off the track by magnetism--either repelled by a track below or attracted by a track above the frame of the cars.

They are usually moved by what is called a "linear induction motor." Think of an electric motor--it uses electromagnets and ordinary magnets together to turn electricity into circular motion to make a shaft turn. Now imagine if you took that motor and "unrolled" it, so the magnets in the motor were forced to move in a straight line instead of a circle. That's more or less what they do...
