Permanent magnet applications can be divided into four categories as follows:
Applications that use the tractive and/or repelling force of the magnet to do mechanical work, i.e., the attraction between a magnet and a soft magnetic material, such as a piece of iron or steel, or the attraction or repulsion between two magnets. This category includes the followings:
Magnetic separators, magnetic holding devices, such as magnetic latches.
Magnetic torque drives
Magnetic bearing devices
Applications that use the magnetic field of the magnet to convert mechanical energy to electrical energy.
Generators and alternators
Eddy current brakes (used widely for watt-hour meter damping)
Applications that use the magnetic field of the magnet to convert electrical energy to mechanical energy.
Actuators, linear, and rotational
Applications that make use the magnetic field of the magnet to direct, shape and control electron or ion beams.
Magnetic focused cathode-ray tubes
Traveling Wave Tubes
Magnetrons, BWO’s, Klystrons

The purpose of a permanent magnet is to produce flux in the working gap of a device. Obviously all permanent magnetic materials will produce flux, but depending on the application, certain material types, grades and shapes will be more efficient. The followings is for each group of our magnets suitable for:
