Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
Nickel-coated, this Neodymium block magnet weighs 2 grams and has a pull force of 0.3110kg. Gauss 6912, Grade N50, direction of magnetization through height. Dimensions are width 3mm, length 5mm and height 1mm.
These super strong Neodymium block magnets are small but mighty, delivering a greater magnetic strength than other types of permanent magnet. Neodymium magnets provide constant and reliable magnetic hold and their shape means they are perfectly suited to secure attachment inside electric devices, especially sophisticated sensors.
The high-tech electronic equipment we rely on for our day-to-day living, such as smartphones, alarms, sensors and remote controlled devices, rely on the power of small Neodymium block magnets to operate. It’s the tiny block magnets that are used to amplify and electrically transmit sound waves in microphones, speakers and headphone equipment.
The nickel coating protects the strong Neodymium material and prevents corrosive forces from damaging the magnet. As well as their value in high-tech, these magnets are also the perfect partner for artists, modelmakers, craftspeople and in the field of fashion where their sleek appearance and small mass make them ideal for an incredibly broad range of applications.

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.
