Y30BH Ceramic Ring Magnet - 50mm O.D x 25mm I.D x 10mm thick - 11.03lbs Pull

• Each magnet's north and south poles are on opposite circular faces.
• Each magnet can support 11.03lbs 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 ferrite magnets, ceramic 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 180 degrees Celsuis. 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.
