Neodymium block Magnets

Block-shaped magnets with long, thin dimensions and poles at each end are sometimes called ‘Bar’ magnets and make good educational tools for explaining the path of magnetic fields. Powerful rare earth Blocks usually have the poles on the wide narrow surfaces and are well suited to clamping and holding steel items together during metal fabrication or manufacturing processes. Block magnets are also used inside metal debris retrieval tools and in wall-mounted magnetic tool holding racks. Many other electrical devices, including electric DC motors, computer hard drives and audio and communications equipment use rare earth Block magnets. Products that use Neodymium Block magnets aim to benefit from their immense strength and compact size which leads to better performance by the product itself. These qualities have made Neodymium magnets irreplaceable components for the designers of modern, high-tech consumer products. Market-leading manufacturers of mobile phones, computers, headphones and speakers all rely on the unique power of Neodymium magnets to ensure their products perform at the highest level.

 

Hundreds of turbines have been built to Hugh Piggott designs around the world. And the magnet he uses in the "A Wind Turbine Recipe Book" is 46x30x10mm Neo magnets.

Production Flow Diagram
Demagnetization Curves
Surface Treatment

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.

Range and Tolerance

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.

Magnetic Properties

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.
