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. China Factory Directly Selling Ferrite Magnet For Speakers
