Neodymium Block Magnet - 25mm x 25mm x 12.5mm
Magnetic Product Description:
This rare earth block magnet has a length and width of 25mm with a thickness of 12.5mm. It has a magnetic flux reading of 5010 and a pull force of 12.25 kilos. It has the AMF magnet part number 22010.
Uses for our rare earth block magnets:
This Neodymium block magnet is magnetised axially through the square-shaped face of the magnet. This particular block magnet also lends itself well to those working with Imperial measurements as the dimensions are very similar but not an exact match to an Imperial 1” x ½” block. The relative nature of the dimensions with the square face and half-height dimension make this magnet versatile as it can be used as a singular magnet or doubled up to make a cube-shape with approximately 30% more magnetic power. The physicality of this Neodymium block magnet makes it easy to handle and stack or remove individual magnets in order to modify the pull-force as required.

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.
