Magnetic Product Description:

This Rare Earth ring magnet has an outside diameter of 16.5mm, an inside diameter of 4.5mm with a surrounding countersunk diameter of 8.5mm, and a thickness of 6mm. It is identified by the AMF magnet part number 23008B.

Uses for our Rare Earth ring magnets:

Plastic-coated Neodymium Rings with a convenient countersunk attachment hole are one of the most versatile magnet(s) available. They are manufactured in matching North to South pairs, so when secured with a screw into any material, they attract. This makes them ideal for creating a soft-close latch mechanism on drawers or cupboard doors. Used as a pair, they eliminate the need for metal surfaces or contact plates altogether so any two surfaces, like timber and plastic for instance, can be bonded magnetically. The plastic coating on these rings increases their versatility by making them weather and shock resistant. This makes them ideal for use on farms, recreation areas, marine environments or wet areas. Outdoor lighting. film props, service tools or camping equipment can be suspended, removed and replaced quickly and without tools or access to power. Paired magnets with countersunk holes for attachment solve a lot of fastening and closure problems, especially where a ferrous material is absent.

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.
