Neodymium Ring Magnet OD25mm x H2mm | Hole 10mm N38
Neodymium Ring Magnets
Outside Diameter: 25mm
Height: 2mm
Inside Diameter: 10mm
Grade: N38
Coating: Nickel (Ni)
Magnetized Direction: Through height – 2mm
Pull force: 2.866kg
Surface field: -1,344 gauss
This rare earth ring magnet has an outside diameter of 25mm, an inside diameter of 10mm and a thickness of 2mm. With a grade of N38, this permanent magnet has a pull force or magnetic force of 2.8kg.
Neodymium magnets are the strongest type of magnets on the market and they come in a range of different shapes and sizes.
Strong magnet rings are an important part of many devices as they provide superior accuracy and precision. When fitted externally over a shaft or internally inside a tube, they work as a magnetic ring sensor which guides moving mechanical elements into the correct position.
Rare earth ring magnets are an adaptable magnet for use around the home or in DIY projects. The hole in the middle provides an easy method to attach the magnet. The North and South poles are present through the flat faces of this axially magnetised ring.
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.
