Neodymium sphere magnets are commonly used in magnetic couplings, bearings, medical devices, educational models, and prototyping applications that require uniform magnetic fields and rotational freedom.

Yes, like all magnets, sphere magnets have a north and south pole. However, due to their symmetrical shape, the poles are not fixed on one face and instead shift based on how the sphere is oriented in space.

Neodymium sphere magnets are made from the strongest magnetic material commercially available. Their pull force varies depending on size, but they offer high magnetic strength relative to their volume.

Yes, neodymium sphere magnets are often used in medical devices and diagnostics, but for implantable or biocompatible use, custom coatings and engineering considerations are required. Contact us for support with medical applications.

While they are safe for most industrial and educational uses, sphere magnets should be handled with care. They can snap together forcefully, posing a risk of pinching or breaking, and should be kept away from children and sensitive electronics.

Sphere magnets are available with several coating options, including nickel, gold, chrome, and silver. Nickel is the standard for durability and corrosion resistance, gold provides excellent biocompatibility for medical and sensitive applications, chrome offers a hard and wear-resistant finish, and silver gives both strong conductivity and a premium appearance.
