This rare-earth sphere magnet has a diameter of 10mm. It is identified by AMF Magnet part number S-D10-N35.
Rare earth magnets come in a range of shapes and sizes including ball magnets. AMF stocks Neodymium Sphere magnets in a range of diameters from 6.35mm to 25mm. The reduced area of magnetic contact created by the curved surface means the magnet has less holding power however is easy to remove and relocate.
Simply roll these cheap magnetic balls across a flat metal surface when you want to reposition them, perfect for whiteboards. Neo ball magnets are used in sensors and switches where they activate processes magnetically. This sphere is supplied in N35 Grade and both north and south poles are present out opposing sides of the curved sphere.
IMPORTANT: These sphere magnets are a swallowing hazard and are not suitable for children.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
