Neodymium Ring Magnet - (OD)25mm x (ID)10mm x (H)10mm | N35
Magnetic Product Description:
This Neodymium (Rare Earth) Ring Magnet has an outer diameter of 25mm, an inner diameter of 10mm, and the height of 10mm. It is identified by the AMF magnet part number R-OD25H10ID10-N35.
Uses for our Rare Earth Ring Magnets:
Neodymium magnets are the strongest available and Ring-shaped Neodymium magnets, like this 25mm wide item, are considered by many to be the most practical shape of all. Strong permanent Ring magnets are easy to attach with wire or string, making any type of material, including non-ferrous ones like plastic or wood, able to bond with a metal surface. To make seasonal decorations or outdoor lighting attach to ferrous surfaces magnetically, simply attach a few Ring magnets with any rope-like material that is at hand. Steel framed pergolas, carports, garages, sheds or clotheslines can be ideal locations for magnetically hanging your party items. When the celebrations are over, they can be instantly removed without damage to any surfaces.

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.
