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.
A Japanese magnetic levitation train has broken its own world speed record, hitting 603km/h (374mph) in a test run near Mount Fuji. The train beat the 590km/h speed it had set last week in another test. Maglev trains use electrically charged magnets to lift and move carriages above the rail tracks.
