ABSTRACT:
A light-weight permanent magnet structure having a permanent magnet shell that generates a high-intensity internal magnetic field that can be accessed without disrupting the uniformity of that internal field. Particularly, the permanent magnet shell is comprised of permanent magnet material that has a uniform magnetization at each polar angle around the shell, such that its size is minimized in regions where less than the maximum available magnetization of the material is required to maintain the internal field intensity. The resultant structure is a lightweight, low profile, low-cost distortion-free flux source that is easier to construct than the prior art.
