This nickel-plated Neodymium block magnet weighs 0.01kg and has a pull force of 25.8kg. Gauss 3047, Grade N42. It is 25mm in width, 50mm in length and 10mm in height. Its direction of magnetization is through height.  

This Nickel-plated Neodymium block magnet weighs just 0.01kg but has an incredible pull force of more than 28kg. These shiny Neodymium block magnets are the powerhouse magnets, able to take on tasks from acting as sensors in industrial and manufacturing processes, to metal clearance and detection where there is a risk of interference with machinery or function. Alarms and security systems also use these super-strong Neodymium block magnets. They can maintain the function of important security and safety system using their natural magnetic power which is not reliant upon mains electricity. Magnetic switches, valves and friction-free magnetic couplings also rely on Neodymium permanent magnets to operate reliably and efficiently. 

These rare earth block magnets are also used in countless applications across many other industries, from outdoor signage to electronics, renewable energy projects such as wind turbines, avionics and the automotive industry.  

Typical Physical Properties

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.
