Magnetic Product Description:
This block magnet has a length of 25mm, a height of 3mm and a width of 9mm with a magnetic flux reading of 2520 Gauss. It has a pull force of 3.3 kg and is identified by the AMF magnet part number 22020.
Uses for our rare earth block magnets:
This strong Neodymium Block Magnet is particularly popular with sign companies, valued for its long shape and low profile which make it the ideal size for placing around the edge of a metal sign box. These powerful blocks enable quick and simple removal of clear covers for cleaning or replacement of advertising posters as new campaigns commence. Café owners also find these a convenient method of attaching menus and whiteboards to café walls, safe in the knowledge that their robust holding power will mean they are not accidentally dislodged.

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.
