摘要：
A variety of promising permanent magnet structures based upon the magic cylinder and magic mangle concepts are investigated with regard to their suitability for application to electrical generators and motors. Such structures feature high magnetic flux densities in large volumes relative to their masses and bulks as well as minimal stray fields and net magnetic moments. Magic mangles also afford small moments of inertia of their rotating elements thereby resulting in improved rotational responsiveness. One computer calculation showed that a small conventional electric generator can be replaced by a magic mangle with 70% more flux amplitude but with only one half the mass and bulk.
