ABSTRACT:
A high field strength permanent magnet has a plurality of layers, with at least two of the layers being formed of materials of different remanence. The remanence of the material of each layer is no greater than that of the layers thereunder, and is preferably less than the remanence of all underlying layers.
The inner layer may be formed of a magnetic structure in which all or part of a basic yoke has been replaced by a shunt of active material. Such a shunt may alternatively be employed in a single layer magnetic structure.
