Magnetic Product Description:
This Rare Earth disc magnet has a diameter of 12mm and a height of 5mm. It has a magnetic flux reading of 4225 Gauss and a pull force of 3.9kg. It is identified by the AMF magnet part number 20040.
Uses for our Rare Earth Disc Magnets:
This 5mm thick disc magnet is N42 Grade for extra strength and is easily recessed into standard gyprock or chipboard with glue without weakening the structural integrity of the sheeting material. Also used for metal separation, water conditioning, electric DC motors and generators, magnetic stirrers, metal detectors, tool and knife holders, holding clamps, timber and metal wall stud finders, magnetic health therapy and invisible brochure and binder closures.

Multiple Uses - limited only by your imagination
Used these to hold chisels vertically in my tool cabinet. Magnets behind the timber are invisible, but even the heaviest of my chisels are totally supported.
Excellent product and great service.

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.
