Neodymium Ring Magnet – 14mm (OD) x 9mm (ID) x 3mm (H) | N38
This Neodymium Ring Magnet combines a slim, low-profile design with reliable magnetic strength, making it a versatile choice for a wide range of applications. With a 14mm outer diameter, 9mm inner diameter, and 3mm height, it’s engineered from durable N38-grade neodymium, offering strong holding power while maintaining a compact size.
The ring shape with a central hole makes it easy to mount onto rods, shafts, or fasteners, providing a secure fit in both static and dynamic assemblies. Commonly used in electronic devices, sensor systems, hobby projects, and industrial prototypes, this magnet is ideal for applications requiring precise alignment and efficient magnetic performance.
Key Features:
-
High-quality N38 neodymium magnetic grade
-
Dimensions: 14mm (OD) x 9mm (ID) x 3mm (H)
-
Perfect for electronics, sensors, robotics, and general engineering
-
Easy to mount and position thanks to ring design
-
Delivers strong, stable magnetic force in a compact size
Whether you're building a custom device, upgrading a magnetic coupling, or experimenting with magnet-based mechanisms, this rare earth ring magnet provides the strength, consistency, and versatility your project demands.

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.
