Magnetic Product Description:

This neodymium magnetic Block has a length of 3mm, width of 3mm and a height of 3mm. It has a magnetic flux reading of 6142 Gauss and a pull force of 0.728 kilos. It is identified by the AMF magnet part number B-W3H3L3-N50.

Uses for our rare earth block magnets:

Small, high-grade Neodymium rectangular magnets or cube shaped magnets combine a lightweight and reduced mass product that offers a minimal compromise in magnetic strength. Permanent magnets operate without any external power requirements and, under normal conditions, will provide constant magnetic hold. The silver nickel coating over Neodymium material keeps the surface of the magnet relatively clean and dust-free, which can be important for the reliable operation of electrical equipment.
Small Rare Earth block magnets have a shape that is suited to secure placement inside compact monitoring devices or inside sophisticated sensors. Many modern-day electronic consumer goods rely on the internal power of small Neodymium block magnets to operate reliably. Block magnets can be fitted onto an alloy or plastic right-angled framework to make component parts attach magnetically. Small Neodymium magnets are also used to amplify and electrically transmit sound waves in microphones, speakers and headphone equipment.

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.
