Neodymium Ring Magnet - (OD)12mm x (ID)5mm x (H)2mm | N35
Magnetic Product Description:
This Neodymium (Rare Earth) magnetic ring has an outer diameter of 12mm, and inner diameter or 5mm, and a height of 2mm. It has a magnetic flux reading of 1865 Gauss and a pull force of 1.11 kilos. It is identified by the AMF magnet part number R-OD12H2ID5-N35.
Uses for our Rare Earth Ring Magnets:
The precise level of hold and release force that is needed to operate at a point of magnetic attachment can be obtained with variations in the magnetic grade and also the distance between the North and South poles (thickness or height dimension). For axially magnetised magnets, which is the orientation of most magnets, thicker magnets have more magnetic material between the poles which in turn generates more magnetic holding power. Also, the higher the magnetic grade that is applied to the magnet during production, the more magnetic strength it emits. N52 Grade is the most powerful grade and has the strongest holding capacity. Small ring magnets can be easily attached to ferrous or non-ferrous shafts or rods with a similar inside diameter to make them magnetic or compatible with steel. Small ring magnets can be used to magnetically store or hold small metal tools and implements used by hobbyists, fabricators sculptors or artists.

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.
