Neodymium sphere or ball magnets are made of high-quality neodymium magnets containing the elements neodymium, iron, and boron. NdFeB magnets are permanent magnets and the most widely used type of rare earth magnets. Neodymium sphere magnets are mostly used in voice coil motor, permanent magnet motors, generators, wind turbines, torque couplings, physics classes and other applications. Honsen Magnetics is specialized in manufacturing and supplying neodymium sphere magnets applied in various industrial applications. We supply all kinds of ball magnet, sphere magnets, neo cube magnet etc from very small to big sizes. As the NdFeB easily oxidized, all magnetic balls need surface treatment. Compared with the industrial magnets, magnetic balls own rich types of coatings, such as nickel, gold, silver and a variety of colors of paint. We could pack the ball magnets in different packings like tins, cans, blister packages, leather case, wooden case, etc. The shapes are regular with diameter. If you are looking for ball magnets, you may supply sizes information of diameter and tell us the coating you want . As jewelry, magnetic ball can be combined to a variety of styles of necklace, ring or bracelet to meet the various requirements of fashion icon. As a toy,magnetic ball, also called Barker ball, is a set of 216pcs n35 grade NdFeB magnet balls in the size of 5mm diameter. And of course other dimensions such as D3mm, D4mm, D4.7mm, D5mm, D7mm, D8mm and other diameter are also available to be customized.Unlike traditional building blocks, magnetic balls have magnetic forces to attract each other. As long as you imagine the rich enough, you can piece balls together into the ever-changing shape. If work too long time & tired, under big life pressure, or have too much trouble, you can play about Buckyball. By its deformation, distorted, you can release the pressure. In teaching, buck ball can be used as a teaching tool to improve the imagination of geometric space. However, do not let the children play Buck ball, because they are easy to swallow the ball into the mouth and cause intestinal perforation. High powered magnets are not children’s toys as well, as they may hurt fingers of children. Honsen Magnetics specializes in magnetic ball, available in a wide range of sizes, coatings and materials. If you require a specific size & color, please contact us for a custom magnetic ball quote.
