Uses for our Rare Earth Sphere Magnets:

Spherical magnets have a north and a south pole and are attracted to iron, cobalt, nickel and other ferromagnetic materials, as well as other magnets. Their spherical shape enables them to be used for special uses that other magnets aren't designed for. Sphere magnets are an easy way to make non-magnetic objects magnetic. Adhere a sphere magnet into a polymer clay figure and make a refrigerator magnet or glue a few to the corners of a small whiteboard and you have a refrigerator board, great for making grocery lists and other notes. Glue two to opposite ends of a necklace and you have a magnetic clasp that is much easier to remove than one made with flat magnets. For a chain holder, hang a string of neodymium magnets from an iron nail in the wall. Store your keys and other small metal objects on the end of the string of magnets.

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

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.
