Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 18mm, an inside diameter of 10mm and a height or thickness of 4mm. It is identified by the AMF part number 23008A.
Uses for our Rare Earth Ring Magnets:
The hole or void in a Ring Magnet reduces its overall volume and consequently reduces its strength or holding power when compared to Disc magnets of similar dimensions. The void provides other benefits in terms of attachment and positioning by allowing screws, nails or string to secure it in place in a less permanent fashion. The void also permits the magnet to be slid over rods, lugs or spindles in specialised measuring equipment like alarms, monitors and sensitive warning devices that have important roles in the highly technical Automotive, Aerospace and Scientific Research sectors.

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.
