Neodymium Block Magnet - 25.4mm x 12.7mm x 3.175mm | N45

Magnetic Product Description:

This neodymium magnetic block has a length of 25.4mm, width of 2.7mm and a height of 3.175mm. It has a pull force of 3.81kilos. It is identified by the AMF magnet part number B-W12.7H3.175L25.4-N45.


Uses for our rare earth block magnets:

The dimensions of this rectangular Neodymium block are exactly compatible with imperial dimensions of 1”x ½”x ¼”. This magnet contains high strength N45 Grade Neodymium. Rectangular magnets are suited to metal decontamination, fitment into swarf pickup equipment and for workshop holding and clamping needs. When placed inside a specialised apparatus these Neodymium blocks can be applied to duties such as water purification, electricity generation, retail advertising and removing metal contaminants from passing materials on a production line.
More recently strong Neodymium magnets have been used in advanced medical diagnostic equipment such as MRI machines. This powerful and compact-sized Neodymium magnet also has endless uses around the home and workshop where they can be used for attachment and holding applications.

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.
