Magnetic Product Description:

This rare earth ring magnet has an outside diameter of 22mm, an inside diameter of 7mm and a thickness of 25mm. It is identified by the AMF magnet part number 23003A.

Uses for our rare earth ring magnets:

Neodymium magnets have a great strength to size ratio which makes them a convenient addition to most applications. Neodymium ring magnets have the added benefit of a hole in the centre where you’re able to use a string or wire if necessary. This could be a great solution to hanging small items or threading a cord from A to B without using a permanent fixture which could damage the surface! This ring magnet has a strong pull force which, combined with the helpful thread in the centre, can be great for metal detection purposes. The options are endless with this strong and versatile product!

Excellent Buy

This is a great magnet. I set into the bottom of my scoop and it works well in picking up metals when detecting down the beach. Saves a lot of time! GREAT!

Fits the bill perfectly

Needed to secure a privacy screen without penetrating the main beam and these magnets do a great job. Now we can also pack the screen up if it rains.

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.
