Product Description:

This rare earth sphere magnet has a diameter of 12.7mm. It is identified by AMF Magnet part number S-D12.7-N35.


Uses for our Rare Earth Sphere Magnets:

Spherical magnets emphasise the importance of shape and size in how a magnet performs and to which applications it is suited. Neodymium magnets come in a huge range of different shapes and each different shape suited to its own applications.
The reduced surface area of the ball magnet’s poles means the area of contact is minimised. These chrome spheres are favored in applications where low bond strength is required and ease of mobility is considered important. Rare earth sphere magnets are also popular for ball magnetic toys, science experiments and other novelty applications.

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.
