Applications for neodymium sphere magnets / NdFeB Sphere Magnet, Magnetic Ball Nickel Plated NdFeB Magnet ball magnet chrome plated ball permanent magnet neo ndfeb ball Sphere NIB Magnet
Neodymium sphere magnets work well on pinboards or whiteboards. Even spheres with a diameter of a few millimetres have already a high adhesive force. Not much bigger than a pushpin, but they can hold paper, photos and documents without leaving holes in them. Larger spheres are able to hold thick cardboard or large posters. They can be easily grasped and moved with one hand, which can be tricky with flat magnets.
You can build various sculptures with sphere magnets (maybe in combination with non-magnetic steel spheres): Cubes, rings, figurines, etc. If you add cube or rod magnets, you can even build atoms or molecules.
Sphere magnets make great jewellery (e.g. bracelet, finger ring) or flexible magnetic closures.

Real monster-spheres! I know adults who were not able to separate these magnets from each other. These should be handled with care and are definitely not suitable for children! (No joke!)
Keep in mind: These spheres are coated with chrome (over a nickel base), which makes them especially robust. Nevertheless, you should not let two of these spheres collide together – the pressure on the points of impact will be so high that the coating may be broken-down over time. Orders of multiple spheres will be delivered with a plastic spacer between them.
