In accordance with the principle of repulsion at the same level and attraction at different levels, the source of maglev is generated from it, just as if it were a maglev train.

There are three basic principles of maglev:

1. When the magnetic field is changed when approaching the metal, the electrons on the metal will move and generate current.

2. It is the magnetic effect of current. A magnetic field is generated when flowing in an electric current or electric wire, and the energized coil becomes a magnet.

3. The magnets will act on each other, becoming the same polarity repelled, the opposite polarity attracted.

The maglev train is derived from the three basic principles of the maglev.
