ABSTRACT:
A magnetic circuit with a remanence varying cylindrical magnet having a b and a remanence varying cladding magnet circumscribing the cylindrical magnet creating a longitudinally increasing axial magnetic field within the bore. The cladding magnet has a radial magnetization transverse to the axial magnetization of the cylindrical magnet resulting in a constant magnetic potential along the outer exterior surface of the magnetic circuit.
