Magnetic Product Description:

This rare earth ring magnet has an outside diameter of 72mm, an inside diameter of 32.5mm and a thickness of 13mm. It has a pull force of 60kg. It is identified by the AMF magnet part number 23001.

Uses for our rare earth ring magnets:

Due to the central void that reduces their overall mass. Ring Magnets have less magnetic power than Discs Magnets of the same diameter and thickness. However, the void offers other benefits that are utilised in sensitive devices that position Ring Magnets on shafts or spools enabling them to interact with ferrous materials or electrical signals and provide information on rotational speed and positioning and can also be used to monitor and indicate minute variations in the operation of crankshafts, transmission, traction controls and drivetrains. These sensing devices are invaluable for the development of the Automotive and Aeronautical industries in instruments like Tachometers and Speedometers and in highly accurate measuring equipment like gas, electricity and water meters that are essential in Manufacturing. Ring Magnets on vane-operated shafts in monitoring equipment also help to record wind speeds, revolutions or the flow of liquids in industrial processes.
