Abstract:

A magnetic circuit with a frustum-shaped magnet having a longitudinal bore and circumscribed by a cladding magnet of varying radial thickness with a non-linear outer exterior surface. The cladding magnet is radially magnetized and the frustum-shaped magnet is axially magnetized, resulting in a constant magnetic potential along the non-linear outer exterior surface of the cladding magnet. A laterally uniform longitudinally increasing magnetic field is created within the bore.
