This Neodymium Ring Magnet measures 29mm outer diameter, 10mm inner diameter, and 8mm height, delivering a powerful magnetic performance with excellent durability. Manufactured from N45H grade Rare Earth material, this magnet combines strength with high temperature resistance up to 120°C, making it ideal for both industrial and engineering applications where consistent performance under heat is required.
This product is identified by product code 23003D.
With a surface gauss of -2500 and a strong pull force of 17kg, this heavy-duty ring magnet provides outstanding holding power for demanding projects. Its ring shape is perfect for use in rotor assemblies, couplings, sensors, magnetic bearings, and custom manufacturing systems where torque transfer or rotational balance is essential.
Key Features:
Dimensions: 29mm (OD) x 10mm (ID) x 8mm (H)
Material: Neodymium Rare Earth Magnet, Grade N45H
Pull Force: 17kg
Surface Field: -2500 Gauss
High Temperature Rating: Up to 120°C
Durable design with high strength in a compact form
Applications:
Motors & Generators – reliable in rotor/stator configurations requiring strong magnetic fields.
Magnetic Couplings – efficient torque transfer in industrial systems.
Sensors & Encoders – precise detection enabled by strong magnetic properties.
Engineering & Prototyping – trusted for heavy-duty custom builds and high-heat environments.

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.
