Magnetic Product Description:
This neodymium ring magnet has an outside diameter of 30mm, an inside diameter of 23mm and a thickness or height of 8mm. It is identified by the AMF magnet part number 23018
Uses for our Rare Earth Ring Magnets:
Many modern devices that are battery powered and compact in design utilise Neodymium magnets including Neodymium Ring magnets. Small but powerful magnets can convert electrical power into useful mechanical movement via an electric DC motor. Equipment that uses this technology can include Motor Vehicles, Electric Toothbrushes and everything in between. Where power-to-weight ratios are important, Neodymium is the magnetic material of choice. Multi-rotor flying equipment known as UAV's or drones, use this technology and the lightweight characteristics of Lithium batteries to stay airborne for longer periods and more reliably.

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.
