This Neodymium block magnet weighs 1 gram, has a pull force of 0.4300kg and is nickel-coated. It has a direction of magnetization through side, Gauss 6740, Grade N50. This magnet has a width of 1.7mm, length 5mm and height 4mm. 

With a grade of N50, this Neodymium block magnet has one of the strongest magnetic forces, delivering an impressive pull force of 0.43kg. The magnetic blocks are Nickel-plated, which significantly improves their durability and physical appeal. They’re not just strong, they’re good-looking as well.   

Because they are so small, these small Rare Earth block magnets are ideal for many modern high-tech applications where components must operate within confined spaces. Neodymium block magnets can be found in microphones and speakers in smartphones, and many other high-tech devices that send and receive sound. Small permanent magnets are also used in the microphone and speakers of many intercom systems and two-way radio transmitters. 

These Rare Earth magnetic blocks are also used in technical devices in medicine and electronics where tiny permanent magnets are used to turn on processes remotely.  

Rare Earth block magnets have impacted many engineering and scientific procedures and enabled the research and development of many new designs and innovations.

Production Flow Diagram
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.
