Based on the principle of mutual repulsion at the same level and mutual attraction at different levels, the source of maglev is generated, just like a maglev train.

There are three basic principles of magnetic levitation:

1.When the magnetic field changes as it approaches the metal, electrons on the metal will move and generate current.

2. It is the magnetic effect of current. When flowing in electric currents and wires, a magnetic field is generated, and the energized coil becomes a magnet.

3. Magnets will interact with each other, creating a situation where the same polarity repels each other and the opposite polarity attracts each other.

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