This neodymium magnetic ring is also known as a rare earth ring magnet. It has an outside diameter of 13mm and inside diameter of 5mm and a height of 2mm. Its magnetic flux reading is 1999 Gauss and it has a pull force or magnet force of 1.27 kilos. Magnetic properties of this strong magnet ring include an operating temperature of up to 80 degrees celsius.This Neodymium magnet has a Nickel coating which is the most common coating on Rare Earth magnets.This protects them and will minimise corrosion.
Ring magnets have a wide range of uses. They can be located on a round shaft or round pin that matches the rings inside diameter. The small hole in the centre of a ring magnet also makes it simple to attach to another surface with thread or a length of wire.
When used as pairs and positioned with opposite poles, they can be used as a closure if placed on either side of a garment. Another example of use is to magnetically join components of a scale model or other consumer products.
Other modern uses of the Neodymium ring magnets include wind turbines, power tools, electric generators, electric motors, motor vehicle ABS systems, and all sound amplification and communication equipment.

Surface Treatment

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.
Range and Tolerance

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.
Magnetic Properties

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.
