Abstract

A permanent magnet structure comprises a flux source having a central cav wherein a highly uniform magnetic field is produced of radial orientation. The flux source comprises a pair of radially magnetized discs of MR material. The discs are coaxially aligned parallel to and separated from each other a given distance. A ring fabricated of passive ferromagnetic material circumscribes the peripheries of the discs, and cladding magnets cover the planar exterior surface of each disc.
