Abstract: This invention provides an electromagnetic device arranged to levitate and move a wheeled-vehicle over a waterless surface with a minimum energy expended. The electromagnetic device comprises: an endless belt which contacts the surface over which the vehicle is moved; a series of magnets positioned on the belt's inner surface which repel other series of magnets suspended from the vehicle body and axles; a set of wheels on the axles which engage a track positioned between the series of magnets on the inner surface of the belt; and a set of electric harnesses arranged to polarize the series of magnets, whereby they repel each other to transfer the wheeled-vehicle weight from the axles to the endless belt.
