Neodymium Block Magnet - 20mm x 12.5mm x 4.6mm
Product code: 22022
Neodymium Block Magnet - 20mm x 12.5mm x 4.6mm
Magnetic Product Description:
This rare earth magnet has a length of 20mm, a width of 12.5mm and a thickness of 4.6mm. It has a magnetic flux of three thousand and ten Gauss with a pull force of 5.7 kg against five mm mild steel. It is identified by the AMF magnet part number 22022.
Uses for our rare earth block magnet
These types of Neodymium permanent magnets are compact and strong. They can be glued to plastic moulds or attached to metal frames so metallic or magnet enabled plastic sheeting can be held in place and removed with ease. This can be extremely useful for the designers of Prototypes or Model makers. They are used in a variety of applications including converting electrical energy into mechanical energy in electric motors found in cordless power tools, generators and electric vehicles.

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.
