Claim:
1. A method for accelerating and decelerating a vehicle, the vehicle including a first magnet mounted thereon, the first magnet being an electro-magnet generating a vehicle magnetic field, the method comprising: positioning a plurality of stationary second magnets along a path of the vehicle, the second magnets being electro-magnets; selecting, to decelerate the vehicle, a first subset of the second electro-magnets based on a desired deceleration of the vehicle; generating, by the first magnet, an electric current having a magnitude calculated to generate in the first subset of second magnets, an induced magnetic field opposed to the first magnetic field as the vehicle passes the first subset of second magnets, a magnitude of the induced magnetic field being selected to achieve the desired deceleration of the vehicle; selecting, to accelerate the vehicle, a second subset of the second magnets based on a desired acceleration of the vehicle; and providing to the second subset of the second magnets an electric current controlled to create a generated magnetic field having a magnitude selected to achieve the desired acceleration of the vehicle.
