Neodymium Block Magnet - 15mm x 5mm x 5mm | N45

Magnetic Product Description:

This neodymium magnetic block has a length of 15mm, width of 5mm and a height of 5mm. It has a pull force of 3.03 kilos. It is identified by the AMF magnet part number B-W5H5L15-N45.

Uses for our rare earth block magnets:

This N45 Grade Neodymium block weighs only 15 grams yet has the magnetic power to support weights up to 3kg! This extreme power to weight ratio typifies the characteristics of Rare Earth Neodymium magnets that make modern technological advancements around the world possible. Stronger magnetic fields produced by compact, lightweight, permanent magnets lead to more practical consumer products that are lighter in weight with higher capabilities than preceding designs.

Neodymium block magnets are used to generate energy in cordless power tools, DC electric motors, generators and to produce sound in audio equipment like microphones and speakers. Electrically powered products that do not have access to mains AC power can make considerable energy savings by using permanent magnets for power generation combined with electromagnetic fields. The power generated from electric motors using permanent Neodymium magnets can reduce costly mains electric power requirements and reduce the drain on battery capacity for electric and hybrid vehicles, electric bicycles, scooters and many other battery powered modes of transport.

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.
