Spherical solid NdFeB magnetic ball is a solid spherical permanent magnet product made of high-purity NdFeB magnetic materials through ball milling, precision grinding and surface finishing treatment. The product adopts a fully solid spherical structure with regular shape, uniform stress and omnidirectional uniform magnetic field distribution, which is different from all flat and special-shaped structural magnets. As a special spherical magnetic component in the NdFeB series, the solid magnetic ball has the characteristics of 360° omnidirectional magnetism, free rolling and arbitrary adsorption, and has unique application value in intelligent assembly, magnetic induction experiment, precise positioning and creative equipment. The product has complete diameter specifications, ranging from millimeter-level small balls to centimeter-level large balls, and can meet the use needs of different scenarios.

In terms of performance and structural characteristics, the spherical solid NdFeB magnetic ball has ultra-high magnetic strength and stable magnetic performance, retaining the high magnetic energy product of rare earth NdFeB materials, with strong omnidirectional adsorption force and no magnetic field dead angle. The standard spherical structure ensures uniform stress in all directions, no deformation and no cracking during adsorption and collision, with good mechanical stability. Compared with irregular magnets, the magnetic ball can roll freely and adjust the adsorption angle automatically, realizing flexible adsorption and arbitrary assembly, which is very suitable for variable and flexible working scenarios. The surface of the magnetic ball is polished to a mirror smoothness after multi-channel precision grinding processes, with no burrs or sharp corners, good hand feeling and strong wear resistance. Through multi-layer nickel plating and passivation treatment, the product has excellent oxidation resistance and corrosion resistance, will not rust and demagnetize after long-term exposure to air and humid environment, with long service life. In addition, the solid spherical structure has high density, strong structural stability and not easy to damage, which can adapt to repeated rolling and collision use.
