Neodymium Ring Magnets

Neodymium Ring Magnets Ring-shaped magnets are popular with customers who like the increased attachment options they offer compared to their Disc or Block shaped relatives. In many applications, the central hole of Ring shaped magnets can be used to keep the magnet securely in the correct position. The hole can fit over pins, lugs or on shafts with a similar diameter to hold the ring magnet securely, while at the same time eliminating the need for fasteners and adhesives that can fail or prove less reliable over time. Fitting Neodymium ring magnets in this way means they can be more easily incorporated into the design and operation of many modern devices and electronic goods and can also be used to generate electrical energy or convert it into physical movement in the case of electric motors. The powerful nature of Neodymium means the magnetic fields of these magnets can penetrate through surfaces and exert magnetic influence from beneath the moulded plastic cases of computer equipment and other modern devices. Magnetic switches, sensors and microphones perform much more accurately and reliably when the magnets are attached in this way and the hard plastic casings of many of these electronic products also reduce the risk of the magnets inside becoming damaged or broken. The strong magnetic power of Neodymium is permanent and may never need to be replaced. This in turn gives these products a high level of efficiency and reliability.

Demagnetization Curves
Surface Treatment

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.

Range and Tolerance

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.

Magnetic Properties

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.
