Neodymium Disc Magnet - 12mm x 10mm

Magnetic Product Description:

This rare earth disc has a diameter of 12mm and a height of 10mm. It has a magnetic flux reading of 5402 Gauss and a pull force of 5.08kg. It is identified by the AMF magnet part number 20025.


Uses for our rare earth disc magnets:

Rare Earth Neodymium magnets are the most powerful permanent magnets commercially available and are the ideal magnet if you require maximum magnetic strength. They are up to seven times stronger than traditional magnets of the same dimensions. This Axially magnetised disc magnet is a perfect example of the strength of these magnets. Due to its height and diameter relationship, this magnet is close to a cylinder in shape, mean the pulling / repelling force of this magnet is concentrated through the flat polar ends. The height of 10mm is almost matching the pole diameter and this significantly increases the magnetic force it produces and therefore, its holding ability. Its compact form makes it ideal for embedding into timber or plastic for a flush finish.  This magnet can also be found in many mechanical applications and their diminutive size means they are incredibly adaptable, they can be used as a singular magnet or in combination to suit the dimensions needed for each application.

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.

yes

They are very good. But it does not have a pull force of 5.08KG and they chip very easily. Not the best magnets but still very good.
