Neodymium magnets in the form of a sphere are called ball magnets. Neodymium magnets in general are characterized especially by their strong magnetic force, which ensures that even very small magnetic balls can already hold heavy weights. A single ball magnet can therefore already attach several pieces of paper to a metallic surface. Their silver alloy also gives neodymium magnets a high-quality appearance. For this reason, it should be avoided at all costs to let individual magnetic balls repeatedly bump into each other too strongly, as otherwise the coating will come off and the sphere magnet may shatter.
