<p>Provided are a plurality of composite permanent magnet magnetic assemblies, in particular to a planar composite permanent magnet magnetic assembly or a cylindrical composite permanent magnet magnetic assembly; the planar composite permanent magnet magnetic assembly is formed with a Tai Chi-shaped magnet and planar Eight-Trigram-shaped magnets horizontally arranged on the same level and combined together, the magnetic field lines all being oriented perpendicular to an arrangement plane; the cylindrical composite permanent magnet magnetic assembly is formed with a Tai Chi-shaped magnet and Eight-Trigram-shaped magnets combined together, and is an axial cylindrical annular arrangement forming a cylinder, the magnetic field lines of the Tai Chi-shaped magnet being in the axial direction perpendicular to the magnetic field lines of the Eight-Trigram-shaped magnets. With a simple structure and a low production cost, the composite permanent magnet magnetic assembly has a better magnetization effect.</p> |
