ABSTRACT:
Two magnetic circuits are separated by an air gap and are made up respectively of a series of permanent magnets which are attached and rigidly held together by flux return yokes. One side of the magnetic circuits is turned towards the air gap. The directions of magnetization of the opposing magnets and of the attached magnets are antiparallel and the length of each magnet is approximately two times larger than the width of the air gap.
