Magnetic Product Description:
This small rare earth ring magnet has an outside diameter of 5mm, an inside diameter of 2.1mm and a thickness of 5mm. It has a pull force of 776 grams. It is identified by the AMF magnet part number 23025.
Uses for our rare earth ring magnets:
This Neodymium Ring is delicate but strong due to the slightly higher N42 Grade magnetic material it contains. Small strong rings are handy fasteners for people who make models for private or civil project designs and also for the hobbyist. Their capacity to hold and release with the application of moderate pressure means individual sections or specific items can be moved, repositioned, relocated and replaced instantly to gain a better perspective or appreciation of different placement options. These hollow cylinder-like magnets can be inserted into a base surface so metallic model parts can be attached or otherwise attached to footings of model parts themselves and used to attach to other magnets. There are numerous other helpful applications for these versatile rings around the home, workshop or office where they will attach to metallic surfaces or even to each other in a North to South arrangement.

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.
