EMS- Electromagnetic Suspension

    This type of Maglev depends on attractive force. With this method, the electromagnets that are on the vehicle are attracted to the steel rails beneath it, which also have electromagnets attached to them.   The vehicle is completely above the rail, however, the magnets on the vehicle curve beneath the rail. Because the magnets are below the rail, they are attracted upwards, which causes the vehicle to be pushed upwards and "levitate."

EDS- Electrodynamic Suspension

    Unlike electromagnetic suspension, EDS operates through repulsive force. In this instance, a vehicle has a  electromagnet attached directly to the bottom of the vehicle, not below the rail. The electromagnet  gives of a repulsive force in conjunction with electromagnets on the rails, which also causes the vehicle to levitate.
