Order before 1pm to qualify for same day dispatch.
Ring-shaped magnet made with premium N52 Grade Neodymium. The small round magnet has a diameter of 6mm and height of 3mm. The central hole is also 3mm in diameter.
Neodymium magnets of all kinds provide the highest level of magnetic attachment available. This is due to the intensely powerful rare-earth material contained beneath the nickel-coated surface. The N52 Grade rare-earth material found inside this Ring Magnet is the strongest grade available in the Frenergy stock range of magnets. Neodymium materials that are manufactured into a Ring-shaped magnet have distinct advantages over other magnetic shapes and this makes them one of the most commonly purchased magnetic products in the entire Frenergy range.
The central void of the Ring is often used as a simple and convenient way of attaching the magnet to non-ferrous surfaces that other magnets would not bond with. Wire or plastic cable can be used to attach the magnet to practically any surface, instantly transforming them into magnetically compatible material. A Neodymium Ring magnet attached with wire to a wooden gate for instance, allows the gate to bind with a Colourbond fence. It can then be held in the open position as needed. Neodymium Ring magnets are also ideal for use in industrial applications where the void helps to locate the ring in the correct position on plastic lugs or shafts which are typically made from non-ferrous materials like fibreglass, plastic or carbon fibre. Neodymium Ring magnets that can provide excellent holding power from small, compact magnet sizes have increasingly become an important component in modern consumer products where they create higher levels of capacity and efficiency.

Surface Treatment
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.
Range and Tolerance
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.
Magnetic Properties
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.
