Uses for our South Facing Rare Earth Ring Magnets:

In the vast world of magnetic products, there is arguably only one thing more practical and convenient than a Countersunk Neodymium Ring magnet, and this is it. This Countersunk Ring is available in a matching North / South pair. When used in conjunction, the outward faces of each magnet attract and bond together. There is no metal or metallic material required. This simple, yet revolutionary product development means any material can be bonded to any other material with the convenience and simplicity of magnetism. Plastic, Timber, Ceramics or Cloth can be bonded with other materials by attaching these complementary magnets with a flathead screw, wire, cable tie or even string. Although they are most commonly used for cabinetry closures they have the ability to solve a huge number of difficult bonding problems where magnetism is desired but no ferrous metal is present. These paired Rings provide the convenience and efficiency of magnetic hold without the obvious and unsightly appearance associated with hooks, nails, latches, bolts or clips. Be careful not to over-tighten attachment screws!

Excellent solution

Our cat would pry open sliding doors and sharpen her claws on our furniture. We drilled these magnets (N + S) into the ends of our sliding doors so they would snap together when shut. It still enabled our young grand children access whilst keeping the cat out. Works perfectly. Many thanks.

Good product

These little magnets were a bit pricey, but still worth every cent. Really strong and well made.

No FAQ available

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

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.
