High-Field Permanent-Magnet Structures.

Abstract

A hollow hemispherical flux source produces a uniform high field in its central cavity. The hemisphere is comprised of a selected magnetic material whose magnetization is azimuthally symmetrical. The magnetic orientation (alpha) in the hemispherical permanent magnet shell is given by the equation: alpha = 2. Theta where Theta is the polar angle. A planar plate of high saturation, high permeability material closes the open end of the hemisphere. An axial bore hole through the hemisphere and/or through the planar plate provides the requisite accessability.
