Neodymium Block Magnet - 40mm x 10mm x 10mm | N48

Magnetic Product Description:

This neodymium magnetic block has a length of 40mm, width of 10mm and a height of 10mm. It has a pull force of 15.41 kilos. It is identified by the AMF magnet part number B-W10H10L40-N48.

Uses for our rare earth block magnets:

This N48 Grade Neodymium block may be relatively compact in form however it has the magnetic power to support weights up to 15kg! It is exactly this power to weight ratio which has allowed Rare Earth magnets to lead engineers and designers to make major advancements in all sorts of modern technologies. The stronger magnetic fields produced coupled with the compact and lightweight form has led to more practical consumer products that are smaller with higher capabilities than preceding designs.
Neodymium block magnets are used to generate energy in cordless power tools as well as electric generators and motors. They are also a key component of most types of audio devices like microphones and speakers.
The power which can be generated from electric motors using permanent Neodymium magnets can greatly reduce the cost and reliance on mains electric power. This can be seen in the reduction in the drain on battery capacity for newly developed electric transport motors such as those used in hybrid vehicles, electric bicycles and scooters.

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.
