Magnetic Product Description:

This rare earth ring magnet has an outside diameter of 12.5mm, an inside diameter of 3mm with a countersunk hole through the north face and a thickness or height of 6mm. It has a pull force of 3.9kg. It is identified by the AMF magnet part number 23012.

Uses for our North Facing Rare Earth Ring Magnets:

There is 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 countersunk faces of each magnet attract and bond together. No metal or metallic material is 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 flat screw, wire, cable ties or even string when resources are stretched. Although they are most commonly used for cabinetry closures, they have the ability to solve a 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 of hooks, latches, bolts or clips.

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.

Excellent

I needed small but powerful magnets to hold a strait-edge on steel for a plasma cutter. They are perfect and so strong.

Lets go fishing

I have made fishing rods for my Joey Scouts and needed small magnets that I could thread and attach to my poles. Perfect !!

Now.....fish or no fish - paperclip or staple within koowee is safe from my FisherScout Joeys.
