Neodymium Ring Magnet - 12.5mm (OD) x 6mm (H) | NORTH Countersunk Face 3mm/6mm (ID)

Neodymium Ring Magnet Product Description:

Similar to Disc Magnets in shape, this strong magnetic ring is distinguished by its countersunk hole. This product has an outside diameter of 12.5mm, an inside diameter of 3mm (to 6mm) and a countersunk hole through the north face. It is 6mm thick, providing a compact shape for small areas. This product is super strong for its size with a pull strength of 3.9 kilograms. It is identified by the AMF Magnetics part number 23012B.

Uses for our Strong Neodymium Magnetic Rings:

Popular with kitchen and bathroom designers/builders, magnets provide easy construction in a concealed manner. Rare Earth Neodymium Ring Magnets are often used as a hidden fixing method for kitchen and bathroom cabinetry, as well as in bench tops. These permanent magnets can create soft door closures in a compact and discreet way. Ring Magnets provide a sophisticated alternative to the four-inch nail. Their magnetic strength is ideal for holding, fixing and releasing of different materials. These materials include stone, timber, ceramics, plastics and fabrics. These ring magnets are also regularly used as fixing methods in school science projects and productions. As well as in advertising and display companies for the purpose of presenting products, services and signage.

Hi Chan,

That's wonderful to hear! We're delighted you found these 12.5mm ring magnets to be such a strong addition to your project. The N50 grade neodymium really does deliver impressive magnetic strength, and the countersunk design makes them perfect for so many applications.

It's great to know you're already planning to buy again - that's exactly the kind of feedback that makes our day!

Thank you for the 5-star review and for choosing AMF Magnetics!

Best regards,
AMF Magnetics

As a user of Neodymium magnets since the 90s, I have sourced them from numerous suppliers. AMF have delivered accurately calibrated magnets, well packaged, posted quickly. The quality of the magnets appears high; they are not prone to chipping and shattering like the cheaper variations. Happy to recommend

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.
