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. In still another embodiment the permanent magnet element is mounted on a wheel which is turned as a result of the interaction of flux produced by the element and that produced independently thereof along an arcuate passage through which the element is propelled on the wheel as it is driven in rotation thereby. In whatever form the invention may take, which as presently contemplated may be manifold, it is to be noted that the moving element is in each case a permanently magnetized member, the physical nature of which affords the invention numerous applications in the useful arts, and the field providing its propulsion is primarily produced entirely independently thereof.
