Abstract: A magnetic propulsion device which provides a magnetic field in which a permanently magnetized conveyor element is caused to have translatory motion as a unitary body. Operation of the device does not depend on induced magnetism in the moving element or in the production of the field which provides the propelling force for the element, such field being produced as by permanent magnets independently thereof. In several forms of the invention the permanent magnet element is suspended by repulsion forces and simultaneously propelled by attraction forces along a passage within the field. The magnetic elements producing the field are variously arranged to provide the propulsion as by lining the passage with magnetic strips of alternating polarity to produce repulsion and attraction forces of differing degree on the moving element or with magnetic members of a single polarity to produce a continuously increasing field of attraction for the element which is propelled thereby.
