Product Description:

This rare earth sphere magnet has a diameter of 15.87mm. It is identified by AMF Magnet part number 61052.


Uses for our Rare Earth Sphere Magnets:

Spherical magnets are versatile and their unusual shape enables them to be used for atypical uses that other magnets aren't suited to. The marble-like shape provides a very small contact area which means the magnetic bond between the surfaces is easily broken. This characteristic of spheres is complemented by the shape which is easy to grasp and remove. In particular applications, sphere magnets may have considerable advantages over more angular shaped magnets as they provide low-pressure contact and minimal surface impact on the metallic surface they are adhered to. This shape is also popular for simulation and experimental purposes or for novelty, educational or creative ideas where they can be used to build all sorts of shapes and structures.

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.
