Neodymium Ring Magnet - OD13mm x H2mm x ID5mm | N35
Magnetic Product Description:
This neodymium magnetic ring has a diameter of 13mm and a height of 2mm. It has a magnetic flux reading of 1999 Gauss and a pull force of 1.27 kilos. It is identified by the AMF magnet part number R-OD13H2ID5-N35.
Uses for our rare earth ring magnets:
Ring magnets 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. Ring magnets in pairs positioned with the opposite poles facing each other can be used as closures on each side of a garment or to magnetically join components of a scale model or a consumer product.
Nickel coatings on Neodymium magnets help protect the magnet and minimise the effects of corrosion. Many modern devices require permanent Neodymium ring magnets to operate reliably. Wind turbines, power tools, electric generators, reed switches, motor vehicle ABS systems, sensors and servo motors and all sound amplification and communication equipment use Neodymium permanent magnets in their operation.

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.
