A suspended magnet behaves very much like a pivoted coil carrying current in a magnetic field. The continual spin of electrons in the atoms of the magnet provides the magnet with the equivalent of a current in a coil around it. Thus, the long, straight arrow may represent either a pointer...
The magnetic circuit design of the permanent magnet motor is based on the requirements of the magnetic field, rationally selecting the parameters and materials of the magnetic circuit, and designing a magnetic circuit that is feasible in process, meets the requirements, is economical, and can give ...

a magnetic field (air-gap magnetic field) formed in a gap between the magnetic circuits is superimposed by magnetic fields from the magnets for perpendicular magnetization as well as a magnetic field from the magnet for horizontal magnetization (in-plane magnetization). The pole faces of the magne...
