Neodymium Block Magnet - 25.4mm x 6.35mm x 76.2mm | N42

Magnetic Product Description:

This rare earth block magnet has a length of 76.2mm, a width of 25.4mm and a thickness of 6.35mm. It is identified by the AMF magnet part number B-W25.4H6.35L76.2-N42.


Uses for our strong rare earth block magnets:

Rare Earth Block magnets have the highest magnetic strength of any magnetic material. Strong Neodymium block-shaped magnets provide levels of magnetic adhesion far greater than their physical size would suggest. Large, powerful Neodymium block magnets have influenced the recent direction of medical and scientific research including their important role in MRI technology. Block magnets are also commonly chosen as major components in apparatus used to lift, collect and separate out metallic material from non-metallic material. Strong Neodymium magnets are also crucial in the operation of electric motors and generators. The permanent nature, compact size and immense strength of Neodymium is harnessed and used to convert electromagnetic fields into the mechanical movement required to drive an electric motor. The repelling and attractive forces of powerful permanent magnets are used to create this movement or, when used in reverse, to generate electricity that can be stored in batteries. This block has metric dimensions that can precisely substitute for imperial 3-inch x 1-inch x ¼ inch measurements.

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.
