Magnetic Levitation Trains

Magnetic levitation, or MagLev is a technology that uses electromagnets to lift a train off the tracks, to eliminate friction. This system has been introduced on trains in Asian countries and manny European countries. It works pretty simply, it’s like a normal train, except without wheels and an engine, it has magnets that hover above the rail enough to lift the train.

The reason that this works so well is because the reduction in friction caused by a wheel on a rail is completely avoided and replaced by a zero friction system of electro magnetics. This allows the train to both levitate off the repulsion of magnets but also propelle the train using rapidly switching magnets.
