This rare earth ring magnet has an outside diameter of 14mm, an inside diameter of 7mm and a thickness or height of 5mm. It has a pull force of 3.5 kg. It is identified by the AMF magnet part number 23009.
Mechanical and Electrical Engineers integrate Neodymium Magnets into the design of nearly all modern-day appliances, including these Ring Magnets. The intense strength of Neodymium material, discovered in relatively recent times, has played a large role in the size and weight reduction of modern high-tech equipment such as that found in Robotics, Electric and Hybrid motor vehicles, electronic devices and Medical and Scientific equipment. Light-weight designs with increased efficiency offer new possibilities for developers of new technologies to improve on outdated and increasingly inadequate equipment. Ring Magnets, in particular, have the unique ability to be positioned on shafts or rods without the need for other fasteners to secure them. The shaft allows some movement to occur due to interaction with the magnetic field and this can be used to accurately measure changes in operating conditions. These properties are used in monitoring equipment like gauges and valves that react to pressure, movement or temperature and can be used to start or stop processes at the appropriate time.
I use my new magnets to attach cnc plasma cut signs to any available surface for photo opportunities.
They work really well.
Thankyou.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
