Spherical Magnets
Product Description
Spherical magnets represent the greatest difference between the usefulness of a magnet type and their tendency to entertain. They can be used to find steel nails in floors, as well as for holding many pieces of paper to a steel surface. But when a number of them are bought, they are endlessly diverting.
While similar to the magnets now semi-illegal for sale in Canada [Buckeyballs], these magnets are much more powerful and should be considered as much a child’s toy as an anvil.
Sold individually or as a set of 512 (forming, with some difficulty, a cube with eight magnets to an edge).
Nickel Plating: The standard coating for neodymium magnets is nickel. A coating is necessary because the combination of metals that makes up Neodymium magnets corrodes quickly when exposed to air. Some of our magnets are triple coated with Nickel Copper Nickel (NiCuNi) for extra durability.
NdFeB: This specification describes the composition of the magnet, Neodymium-Iron-Boron, to differentiate between magnet types and facilitate further research if necessary.
Grade: The N rating of a magnet is the way those who deal with magnets on a regular basis denote the strength of a particular magnetic material regardless of its shape. The pull force takes into account the geometry of the magnet as well
Maximum Operating Temperature: NdFeB magnets begin to act unpredictably at temperatures above 80°C (176°F). They will lose their (permanent) magnetic properties at around 200°C.
