A contactless, multi-dimensional small stepper motor with a maximum dimension of less than about 10 centimeters is described. The motor contains at least one magnetized article, at least one superconductive primary suspending element, and at least two primary conductive elements. Each of the primary conductive elements is separated from each adjacent primary conductive element by a distance of from about 0.01 to about 10 millimeters.
