2. Permanent magnet motor - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet_motor

   Schematic of a permanent magnet motor using brushes and magnets in the stator. A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature.

3. Electropermanent magnet - Wikipedia

   en.wikipedia.org/wiki/Electropermanent_magnet

   An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...

4. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.

   Magnetic locks are almost always part of a complete electronic security system. Such a system may simply consist of an attached keycard reader or may be more complex, involving connection to a central computer that monitors the building's security. Whatever the choice of locking system, fire safety is an important consideration. [2]
