Neodymium Block Magnet - 20mm x 6mm x 3mm | N52
Magnetic Product Description:
This block magnet has a length of 20mm, a height of 6mm and a width of 3mm. It has a pull force of 3.2 kg and is identified by the AMF Magnet part number 22023B.
Uses for our Rare Earth block magnets:
Neodymium block magnets are versatile products that exhibit both impressive strength as well as compact size. This specific Rare Earth Block magnet has a small size of 20mm x 6mm x 3mm but has an incredible pull force of 3.2kg due to the high N52 magnetic grade. The high grade means that the magnet emits a stronger pull force than other magnets of the same size, which in turn makes this magnet ideal for a large range of applications. Commonly used in the signage industry, these Neo block magnets offer a considerable pull force while also fitting seamlessly into the background due to their small size. This style of Neodymium magnet is also often used for sensor applications, in small motors to generate power, and even crafting!

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.
