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).
