Neodymium Ring Magnet – 21xmm (OD) x 14.5mm (ID) x 3.2mm (H) | N45H | High Temperature 120°C
Magnetic Product Description:
This Neodymium Ring Magnet offers exceptional strength in a compact form. With outer dimensions of 21mm, an inner diameter of 14.5mm, and a thickness of 3.2mm, this magnet is made from N45H grade neodymium, designed specifically for high-temperature environments. It maintains its superior magnetic performance even in conditions reaching up to 120°C, making it ideal for demanding industrial applications, motors, sensors, and specialised equipment.
The ring shape provides versatility for a variety of uses, such as mounting or installation in systems requiring a central hole. Known for its remarkable pull strength and durability, this high-temperature magnet is engineered to last without losing magnetism or effectiveness.
Key Features:
- Dimensions: 21mm (OD) x 14.5mm (ID) x 3.2mm (H)
- Magnetic Grade: N45H (High-temperature resistance)
- Maximum Operating Temperature: 120°C
- Ideal for industrial, automotive, and electronics applications

NB: Ranges are indicative for product category, please check individual products for specic values within that range.
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.
