This rare earth cylinder magnet has a diameter of 10mm and a height of 50mm. It has a magnetic flux reading of 6567 Gauss and a pull force of 4.7 kilos. Its part number is 21022.
The elongated shape of this Neodymium cylinder magnet provides a powerful concentrated magnetic field through each of the flat end surfaces. The narrow nature of this field is particularly suitable for applications where stray magnetic field is problematic and reduces the risk of accidental activation of other local devices. The 10mm diameter of this cylinder permits the easy insertion into a drill hole of corresponding dimensions. The shape and grade of a magnet are integral factors in how a magnet performs and needs to be carefully considered. This Rare Earth cylinder is made of N42 grade magnetic material and provides superior performance to magnets of a standard lower grade.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
