ABSTRACT:
Disclosed herein is a composite permanent magnet and a circuit which employs a plurality of such magnets. The composite magnet combines discrete sections of a first magnet material with at least one discrete section of a second magnetic material. The first material has a high residual magnetic strength and a moderate energy product. The second material is many times more expensive than the first material and is characterized by a high residual magnetic strength and a high energy product.
Also disclosed is a circuit combining a plurality of such composite magnets. The circuit combines the above magnets in such a way that there is a reduction in magnetic leakage in the circuit.
