Rare Earth Magnetic DIsc Product Description:

AMF Magnet’s range of Neodymium Rare Earth Magnets is high quality and super strong. This product comes in a popular disc shape with a diameter of 25mm and a height of 5mm.
This powerful magnet has a nickel coating for corrosion resistance and prolonged use. This product has a strong magnetic field and powerful pull strength. This Neodymium Disc Magnet has a magnetic flux reading of 2340 Gauss and a pull force of 9.3 kilos.


Uses For Our Neodymium Disc Magnets:

Neodymium Rare Earth Disc Magnets are extremely versatile and tolerant. They can be used for a wide range of uses in the home and in more specialised industrial settings. Uses for these magnets in the home include all purpose holding and fastening, in fridge magnets and to display art. They are also commonly used in specialised engineering or electrical applications.
Electrical engineers find these extremely strong magnets particularly useful. 25mm x 5mm Disc Magnets are often used alongside electricity, particularly in the form electromagnetism. This process is commonly used to treat hard or contaminated water. Disc Magnets can also be found throughout electrical equipment and electronic products.

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 magnets.....highly recommended.

Used two magnets recessed into a wooden base to hold a 10W LED. Recessed magnets flush with wood, mounted LED bracket, araldite/glued magnets and nuts into place and then covered with rubber. Wired 4 LED lights in a row, attached to outside of 4X4 ( rubber base leaves zero scratches :) ) and connected to battery inside battery box. BRILLIANT and holds very nicely indeed. I also used 2 magnets on the back of my miners pick for when I go metal detecting....pick up crap magnetic targets on the pick to save time digging. Love neodymium magnets....1000 uses indeed :)

Magnets worked well

These 25mm x 5mm magnets were used in pairs, mounted within custom steel holders (made by me) to act as anchors for chain barriers between public and not-public areas of a gallery. The walls were steel and it was preferred to have no drill holes in them for the anchor mounts. Magnets were the solution and these worked very well, very strong.
