Neodymium Ring Magnet - OD5mm x H2mm x ID2mm | N45

Magnetic Product Description:

This neodymium magnetic ring has a diameter of 5mm and a height of 2mm. It is identified by the AMF magnet part number R-OD5H2ID2-N45.


Uses for our rare earth ring magnets:

Neodymium magnetic material offers the highest magnetic strength compared to other permanent magnetic materials. This tiny Ring-shaped magnet is very strong for its size and weight and can be integrated into small products to utilise the magnetic properties. They can activate switches and circuitry as they interact with electromagnetic fields. Small permanent magnets can be used to establish a magnetic bond between two surfaces and avoid the use of conventional attachment methods such as clips, pins or glue.
Magnetic folder closures for hobbyist scrap booking or commercial brochure manufacture are increasing in popularity. Jewellers and costume designers also find magnetic hold a practical and inexpensive option for their creations. Ring shaped magnets and their central hole offer a simple and convenient way to attach the magnet using thread or wire to hold the magnet in place for crafting purposes or can be secured into position by a locating pin in large scale consumer product designs.

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.
