Ferrite Ring Magnet - (OD)72mm x (ID)32mm x (H)15mm

This ferrite ring magnet has an outside diameter of 72mm, an inside diameter of 32mm and a height or thickness of 15mm. It has a pull force of 2.7kg and is identified by the AMF magnet part number 13020. Uses for our Ferrite Ring Magnets:

Ferrite or Ceramic Rings are affordable, corrosion resistant and remain operable at high temperature. They also have a high tolerance for demagnetisation. Ferrite Magnets possess a wide magnetic field that makes them suitable for metal separation purposes as well as metal detection and sensory equipment. Ferrite Rings like these have for many years been employed in the manufacture of audio speaker equipment and PA systems. Although the central hole reduces the volume and surface area of the magnet, the void can be an advantage for fitting over shafts or on lugs or where reduced surface area lowers friction and can help in applications that require quick relocation or removal of the ring.
