Product Description:

This small rare earth ring magnet measures 5 mm (OD) x 2 mm (ID) x 5 mm (T).
It has a pull force of 680 grams. GRADE N38.

IMPORTANT: These magnets are a swallowing hazard and are not suitable for children.

Uses for tiny ring magnets:

These very small magnets, commonly found in electronic equipment, are also used in the practice of modern medicine. If a child swallows a small battery you don't have much time to act. Doctors advise that in as little as two hours batteries can begin to liquefy or dissolve inside the child's body. Some medical practitioners are adapting existing medical equipment to use these tiny neodymium ring magnets to extract batteries and other metallic objects from children's noses, ears, esophagus or lungs. As machines and equipment become ever more sophisticated, magnets provide a reliable and durable hold and release function like no other.

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.
