What does the maglev train use to suspend the train?

Repulsion makes the train suspended, and gravity makes the train move.

Brief introduction of maglev train

Maglev train is a modern high-tech rail transit vehicle, which realizes non-contact suspension and guidance between the train and the track through electromagnetic force, and then draws the train by electromagnetic force generated by linear motor.

Principle of maglev train

There are two forms of maglev train: like magnets repel each other and opposite magnets attract each other, so there are two corresponding forms of maglev train:

1. The maglev train with electromagnetic control system is designed according to the principle that like magnets repel each other. It uses the repulsive force between the magnetic field formed by the superconducting electromagnet on the train and the magnetic field formed by the coil on the track to suspend the train body.

2. The maglev train with electric operation system is designed according to the principle that magnets attract each other. Magnets are installed on the underbody and the upside-down top. An induction plate and an induction steel plate are respectively arranged above the T-shaped guide rail and below the leg part to control the current of the electromagnet, so that a gap of 10- 15mm is maintained between the electromagnet and the guide rail, and the repulsive force of the guide rail steel plate is balanced with the gravity of the vehicle, so that the vehicle body is suspended on the guide rail of the driveway.

Therefore, the maglev train makes use of the principle of "like-poles repel, opposite-poles attract" to make the magnet have the ability of defying gravity, so that the car body is completely off the track and suspended at a distance of about 1 cm from the track, flying in the air, creating a miracle of space flight with almost zero height.
