Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This Neodymium block magnet weighs 20 grams and has a pull force of 11.01kg. Gauss 3509, Grade N45. It is 10mm in width, 50mm long and 5mm in height. The direction of magnetisation is axial (through the height).
This Neodymium block magnet weighs just 20 grams but has a hefty pull force of more than 11 kg. This block magnet has a low profile and flat surface and is made from high grade N45 Rare Earth material. As well as the super strength and holding power of this block magnet, its width and low height means it can cast its magnetic field over a broader surface area, perfect for display retail signage, advertising material, promotional products, brand merchandise, business name signs or any other display item that requires a strong, practical and easy to use method of attachment.
Neodymium Block magnets have no problem getting into the heavy-duty work either. Their bond and release at threshold pressure, or 'quit the grip force'', defines them as virtual torque limiters or an overload clutch. These failsafe mechanisms are vital to protect equipment crash stops and jams. When the excessive force event has been addressed, their magnetic instinct is to re-engage to its original position. These capabilities make the Neodymium block magnet an essential part of many manufacturing processes.
Whenever a reasonable amount of force is required, this style of magnet is the pick of the bunch. Its applications include engineering and industrial uses, water purification, use as commercial door holders, even musical instruments. The Rare Earth block magnet, with its wide, strong magnetic field, has been used instead of the usual spring on drum kits, giving the musician a much better response time – rock on!

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.
