Magnetic Product Description:

This small rare earth ring magnet has an outside diameter of 6mm, an inside diameter of 3mm and a thickness of 3mm. It has a pull force of 0.870 kilograms. It is identified by the AMF magnet part number R-OD6ID3H3-N52

Uses for our rare earth ring magnets:

Neodymium magnets are available in many shapes but Neodymium Ring magnets are probably the most useful and most versatile. Although the absence of magnetic material where the void occurs detracts from a ring magnet’s overall strength, the advantages of the ring-shaped magnet should not be underestimated. Designers of sophisticated electrical devices and equipment find solutions to design problems and create exciting and distinctive new product features by introducing Ring magnets to their design. Laptops, smartphones, electronic devices and electronic equipment of nearly every type, utilise Neodymium ring magnets in their design. The futuristic qualities of small but powerful Neodymium magnets and the use of electromagnetic attraction or repulsion enhances the performance and market appeal of products that use them. Despite their widespread use in electronic product manufacturing, Ring magnets have very practical uses in our more ordinary, everyday lives. Unlike Block or Disc-shaped magnets, the void in a ring-shaped magnet makes a convenient point of attachment. Wire, string, cable ties or rope are simple methods of attaching a Ring magnet to another surface or materials and can be achieved without the usual application of glue, screws, bolts or nails. To attain a precise level of magnetic hold, for instance, additional Rings can be slid onto a wire or threaded onto a cable, until the correct level of magnetic hold is achieved to suit your particular circumstances. This example and various other applications demonstrate the superior versatility and convenience of ring-shaped magnets.

Tiny Ring Magnets

Yea they are good, but I probably ordered too small a size

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.
