Abstract
A yokeless magnetic circuit composed of a permanent magnet shell having a lenoidal-cavity within which a working field is generated. The permanent magnet shell has a conical permanent end magnet adjacent each of its ends to insure that the surface at each of its ends is equipotential between the radial periphery of the permanent magnet shell and the axial centerpoint of the solenoidal cavity. The height of the conical end magnets directly depends of the magnetization and thickness of the permanent magnet shell and whether the internal field is uniform, gradient or variable.
