Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 20mm, an inside diameter of 5mm and a height or thickness of 3mm. It has a pull force of 3.8kg. It is identified by the AMF magnet part number 23015.
Uses for our Rare Earth Disc Magnets:
When it comes to creating a temporary or semi-permanent magnetic bond between surfaces Neodymium Ring magnets are practical and efficient. Rings secured in a non-penetrative fashion with plastic cable ties or wire allows them to be removed at a later date without the surface damage or structural weak points created by traditional invasive attachment methods like nails or screws. Rings can also be stitched or sewn into cloth material or a garment for instant and convenient attachment to non-metallic surfaces, using another magnet with an opposing polarity, or to magnetic surfaces like galvanised iron fencing or scaffolding. Ring magnets of moderate pull force are often used in school projects for educational purposes and in theatrical productions for fast set and costume changes and efficient, simple prop placement.

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.
