ABSTRACT:
Permanent magnets are used to perform useful work. The field of a first permanent magnet is diverted by electromagnetic coils to such a low value that another opposing permanent magnet can approach the first magnet without the application of undue force. The field in the first magnet is restored to act on the second magnet so as to repel it. The force which results may be harnessed to effect reciprocal or rotary motion.
