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 andor through the planar plate provides the requisite accessability.
