This Neodymium block magnet weighs 20 grams and has a pull force of 6.25kg. Gauss 3218, Grade N35. It is nickel-coated. Width 10.00mm, length 30.00mm and height 5.00mm. Its direction of magnetisation is through the height.
Neodymium block magnets are a vital part of so many innovative, technological advancements. The power to weight ratio of these Rare Earth magnets, coupled with their durability, reliability, permanence and compact size means they can be applied to an almost endless array of projects and processes. As the most powerful of all permanent magnets, the intense strength of Neodymium magnets has seen them used in high tech, industrial and, manufacturing processes, DIY, electronics – wherever intense strength and permanent, reliable magnetic force is required.
Neodymium Block magnets can hold all sorts of materials – wood, plastic, fabric, metal, composite - onto flat steel surfaces, and are also responsible for the generation of rotational movement inside electric motors where they react to alternating electric currents. Many mining, agriculture, manufacturing and commercial industries rely on electric motors which in turn function because of the properties of Neodymium block magnets. They are also extremely useful in factories and workshops where the block magnets can be can used to attract and collect harmful metal waste.
For domestic or creative projects, these Rare Earth magnets are ideal, with just a small amount of epoxy glue needed on the back of the magnet to attach it to any type of surface. Square and rectangular shaped Neodymium magnets are often used as crucial components in other apparatus.

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.
