Sphere magnets neodymium

Sphere magnets neodymium Here you can find strong neodymium sphere magnets/magnetic spheres. They are coated with chrome, which makes them especially robust (single exception: K-05-N).

Still, you should avoid crashing them together. The pressure on the small contact areas gets so high that the coating may break over time.

Applications for neodymium sphere magnets

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.

Danger for children

Please note: Due to the danger of swallowing, magnetic spheres are not suitable toys for young children and should be kept out of reach. If several small magnets are swallowed, they may get stuck in the intestine and cause life-threatening injuries.
Large sphere magnets can also lead to contusions due to their high adhesive force, hence, even older children should not handle them.
