Magnetic Levitation

The Principle

The principle of magnetic levitation (MagLev) is that a ferromagnetic body should be kept in levitation by an electromagnet. The force exerted by the electromagnet on the respective body depends primarily on the distance between the body and the magnet and the current flowing through the coil. The counterpart to the magnetic force is gravity, which wants to pull the body to the ground. For detailed information see > Presentation on Maglev.
