- 102mm outer diameter x 51mm inner diameter x 15mm thick
- Each magnet's north and south poles are on opposite circular faces
- Each magnet can support 9kg pull vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness
- Resistant to demagnetisation and corrosion without any extra coating
Also known as ceramic magnets, ferrite magnets offer excellent value for money when pull strength is not the most important factor. They have a high resistance to corrosion and demagnetisation and can operate in temperatures up to 180oC. 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.
