1. A levitation generator comprising:
a member having at least one elongate magnetic pole configured to generate a lifting flux field for intersecting at least a portion of a lifting member of a guideway;
the at least one elongate magnetic pole is oriented at an angle relative to the direction of relative motion of the levitation generator to the lifting member, such that a lifting force component is generated in a direction normal to the direction of relative motion;
wherein the angle is based on a required lifting force and a relative velocity between the levitation generator and the lifting member;
wherein the lifting force is dependent upon the velocity of the at least one elongate magnetic pole relative to the lifting member, wherein a higher velocity produces greater lift.
