Magnets function as transducers, transforming energy from one form to another, without any permanent loss of their own energy. General categories of permanent magnet functions are:
Mechanical to Mechanical – attraction and repulsion. Examples of applications that utilize this are magnetic separators, holding devices, magnetic torque drivers and magnetic bearings.
Mechanical to Electrical – the conversion of motion to electrical energy. Example applications are generators, magnetos, and microphones. Neodymium Motor Rare Earth Segment Curved Magnet
Electrical to Mechanical – the conversion of electrical energy to motion. Example applications are motors, meters, relays, actuators, loudspeakers, and charged particle deflection, traveling wave tubes, ion pumps, and cyclotrons.
Mechanical to Heat – the conversion of motion to heat energy. Example applications are eddy current heaters.
Special Effects – such as magneto resistance, Hall effect devices, and magnetic resonance.
