ABSTRACT:
Truncated clad magnetic structures producing a strong magnetic field within an interior working space and having minimal external flux leakage. Cladding magnets are added to structures which otherwise must be theoretically infinite. The cladding magnets, specially shaped so that their exterior surfaces are at zero magnetomotive potential, permit the use of truncated structures without loss of field strength or uniformity. Cladding formulas give approximate values which can be made more nearly exact by successive approximations in cladding thickness variations.
