During the past decade there has been a marked increase in the attention devoted to achieving noiseless, smooth and efficient suspension systems for use on high speed ground vehicles. The technology of magnetic levitation offers great promise for use in such suspensions; as a result two distinct types of non-contracting magnet systems have been proposed: 1. An attraction system, which suspends a vehicle by means of the attractive force generated between a controlled electromagnet and a ferromagnetic rail. 2. A repulsion system, which utilizes the repulsive levitation force generated by the current induced in a normal conducting guideway as a result of the motion of a superconducting coil carried onboard the vehicle. Each of these techniques has several forms and adaptations which are discussed, the advantages and disadvantages of the various systems are described as appropriate and the present state of various experimental vehicles and test programs is reported. A bibliography is included to help the interested reader obtain information about specific research programs and technical problems.
