Neodymium Ring Magnet - OD50mm x H5mm x ID20mm | N35

Magnetic Product Description:

This neodymium magnetic ring has an outer diameter of 50mm, an inner diameter of 20mm and the height of 5mm. It is identified by the AMF magnet part number R-OD50H5ID20-N35.


Uses for our rare earth ring magnets:

Many AMF customers find Ring magnets the most useful of all magnet shapes. Neodymium Ring magnets make ideal metal retrieval tools. With a length of cord, rope or string attached, a ring magnet can be converted into a tool that is able to access hard to reach places at home, work or on a building site. Suspending this Ring magnet on a rope will allow the North and South poles, that are found on the flat, round faces, to attract and collect any valuable metal objects or debris that falls into the powerful magnetic field. The attached rope allows narrow crevices, deep pits and watery environments to be magnetically explored from a position of relative safety. String or rope can also help attach a Neodymium ring magnet to steel fences, gates and doors to keep them open or closed. Ring magnets are easy to attach to any surface and are the most convenient shape for applications where a temporary magnetic hold is required.

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.
