    Applications for neodymium sphere magnets / NdFeB Sphere Magnet N42
    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, Neodymium magnets, Neo magnets and Neodymium Iron Boron magnets. These terms are all used to describe the same magnetic material – Nd2Fe14B. adhesive ndfeb magnet
    We stock a large variety of shapes and sizes of NdFeB magnets which you can buy online from us. But if you cannot find what you want (e.g. different shape, different size, different grade) or you need much higher quantities, please contact us for a quotation. We can supply custom NdFeB magnets. We can supply high quantities of NdFeB magnet.
    NdFeB magnets are, size for size, the most powerful of all the permanent magnets. They are a Rare Earth magnet type. Because they offer so much performance from such a relatively small volume, NdFeB magnets are almost always a first choice for ambient temperature dry environment applications. NdFeB magnets are extremely popular across many industries.
    We offer 127 grades of NdFeB with over 40 options for protective coating. Nickel plated N35 NdFeB or nickel plated N42 NdFeB (usually NiCuNi coating) are commonly used grade and coating combinations. Other coatings and grades are possible e.g. N52, N30, N42UH, etc; zinc, epoxy, gold, silver, etc.
