Applications for neodymium sphere magnets / NdFeB Sphere Magnet N42, small sphere magnet small ball 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.
Browse through our customers’ application examples that illustrate the many possibilities of sphere magnets.
Neodymium magnets are made of neodymium, iron and boron (NdFeB) and are the strongest raw magnets. We offer different shapes:
Discs, rods, rings, blocks, cubes, spheres (alternatively called balls), flat pots.
If you are not sure which shape or size would be the best for your special need please contact us.
NdFeB magnets are a sintered magnetic material (a jet milled magnet alloy powder compacted in a die press and sintered to fuse the powder before machining, coating and magnetising). Although termed Rare Earth, there is nothing rare about NdFeB magnet material. The rare earth elements are abundant with new material sources being discovered and opened across the globe.
NdFeB magnets are also known as Neo magnets, Neodymium magnets, Neodymium Iron Boron magnets, Neo Rare Earth magnets, NdFeB Rare Earth magnets, REFeB magnets, NIB magnets, Neodymium-Iron-Boron magnets, NdBFe magnets, Neodymium Rare Earth magnets and sometimes Super Strength magnets and Super Power magnets (the latter two names are vague and could be used for other larger magnetic materials so should not be used to name magnet types).
