Ring magnets are made specifically for loudspeaker systems and their sizes have evolved with demand from this market. However, they are also commonly used in magnetic rollers for separating applications and in the printing industry. They are also a vital component found in fast running conveyor systems in many manufacturing plants dealing with ferrous material.

Ferrite magnets, sometimes referred to as ceramic because of their production process, are the least expensive class of permanent magnet materials.Ferrite magnets became commercially available in the mid 1950’s and has since found its way into countless applications including arc shaped magnets for motors, magnetic chucks and magnetic tools.
