Levitation. Maglev trains have no contacts with the rails while they move forward. They are levitated on the guide-way with the help of magnetic forces. Levitation is the process by which an object is suspended against gravity in a stable position without any physical contact.
They are used in the Maglev trains. In the Maglev trains, the super conducting magnets are used on the tracks on which the train floats. These types of the trains are working on the repulsion force of the magnets. They are also used to sort out the magnetic and non magnetic substances from the scrap. They are used in TV screens, computer screens, telephones and in tape recorders. They are used by the candy or cold drink vendors to separate the metallic cap from the lots.
