Abstract
An apparatus designed to move mass without contact is described. The apparatus contains a chamber which is formed by alternating sections of superconducting material and electromagnetic coils. The chamber is cooled to below the critical temperature of the superconducting material, and a magnetic object is disposed in the center of the chamber. A series of coils along the chamber are sequentially energized by direct current to form electromagnetic fields. The sequence and direction of these fields causes the movement of the magnetized object within the chamber.
