Neodymium Ring Magnet OD12mm x H2mm | Hole 5mm N35
Neodymium Ring Magnets
Outside Diameter: 12mm
Height: 2mm
Inside Diameter: 5mm
Grade: N35
Coating: Nickel (Ni)
Magnetized Direction: Through height – 2mm
Pull force: 1.115kg
Surface field: -1,865 gauss
The Neodymium ring magnets, also known as rare earth rings, are available in various sizes and a variety of grades. The higher the grade the greater the pull force for any given size of magnet. The N52 grade is the strongest grade with the highest holding capacity. The amound of magnetic material present, particularly in the distance between the North and South poles (thickness or height dimension) will also determine the strength of pull force. For axially magnetised magnets, which is the orientation of most magnets, thicker magnets have more magnetic material between the north and south poles which in turn generates more magnetic holding power.
The small but strong magnetic ring has many uses. It 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.
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.
