This Neodymium Cylinder Magnet (20mm diameter x 30mm length) is a robust rare earth magnet engineered for strength, precision, and heat resistance. Manufactured in Grade N42H, it offers reliable performance at elevated operating temperatures up to 120°C. With a surface gauss rating of 5879 and a strong pull force of 18.27 kilograms, this cylindrical magnet is an excellent choice for industrial, mechanical, and scientific applications requiring compact yet powerful magnets.
This magnet is identified by product code 21014.
Key Features:
Dimensions: 20mm (Diameter) x 30mm (Length)
Grade: N42H – high strength neodymium magnet with heat resistance
Maximum Operating Temperature: 120°C
Pull Force: 18.27kg – dependable holding capacity
Surface Gauss: 5879
Coating: Triple-layer Nickel-Copper-Nickel (NiCuNi) for durability and corrosion protection
Applications:
The balanced proportions and strength of this neodymium cylinder magnet make it suitable for a wide variety of professional uses, including:
Industrial machinery and automation systems.
Motors, generators, and actuators.
Magnetic separation and recovery processes.
Research laboratories and prototyping projects.
Secure holding, alignment, and fastening applications.
The N42H grade provides an ideal balance of power, durability, and temperature stability, while the NiCuNi coating ensures long-lasting corrosion resistance and a polished metallic finish. This cylinder magnet’s versatile size makes it highly practical for both heavy-duty industrial settings and precision engineering tasks.

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.
