Abstract
A hollow spherical flux source produces a uniform high-field in its central cavity. The sphere is comprised of a selected magnetic material whose magnetization is aximuthally symmetrical. The magnetic orientation (.alpha.) in the spherical permanent magnet shell is given by the equation: .alpha.=z.theta. where .theta. is the polar angle.

A permanent magnet structure comprising a hollow substantially spherical magnetic flux source for producing a uniform high-field in its central cavity, said spherical flux source being azimuthally symmetrical in magnetization, the magnetic orientation (.alpha.) in the substantially spherical magnetic shell being given by:
- .alpha.=2.theta.
- where .theta. is the polar angle.
