Neodymium Ring Magnet - 72mm x 32.5mm x 13mm

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:

This Neodymium Ring magnet is the largest in our range with a strong 60kg pull force it is suitable for commercial use only. Ring magnets are often incorporated as part of a mechanism or machine and utilised for their ability to attract or repel metal or other magnetic material at a specified level of force. Ring magnets traditionally have been used for roles such as detection, separation and purification. They have also been adopted for use in highly accurate measuring devices and sensing equipment utilise ring magnets in their operation. Devices such as these are commonly used in the Aeronautical, Defence, Automotive and Aerospace industries where it is critical that equipment that performs reliable and accurately with minimal margin for error acceptable.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
