    Applications for neodymium sphere magnets / NdFeB Sphere Magnet, Copper Plated NdFeB Magnet ball magnet chrome plated ball permanent magnet ball rare earth 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. Sphere Neodymium Magnet If you are not sure which shape or size would be the best for your special need please contact us.

    Attention: At the end of this category you will find our steel balls because many customers want to have them here – these last three products are no magnets but simple steel balls.

    Holding forces are measured on steel plates (constructional steel of thickness min. 1 cm). Other metallic bonding surfaces or other influences (air humidity, room temperature, vertical position, dirt or dust) might reduce holding force. All declarations are average values.
