Question

How to do magnetic levatation

Answer 1

Magnetic Levitationin which trains float on a guideway using the principle of magnetic repulsion. Each magnet has two poles. Now if you play with two magnets, you'll realize that opposite poles attract, whereas similar poles repel. This repulsive property of magnets is used in Maglev trains. However,instead of using permanent magnets, the principle of electromagnetism is used to create strong and large temporary magnets. When an electric current is passed through a coil of wire, magnetic field is generated around the coil according to Faraday's laws.

Answer 2

Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations.

The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized.

Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes.
