The True Nature of Magnetization

Classical electromagnetism and magnetic domain theory only describe magnetization from macroscopic appearance and attribute magnetization simply to the alignment of magnetic domains. They fail to reveal the underlying physical mechanism of the change of electron motion form behind magnetization. Based on the core model that magnetic field belongs to cylindrical concentric vortex field in the Theory of Light Origin, this paper expounds the true physical nature of magnetization. Magnetization is not the simple unification of electron spin direction. It refers to that a small number of magnetizable electrons in outer layer or sub outer layer of atom change their motion mode from three dimensional spherical shell full range 360 degree disordered shell motion to coplanar circular motion with circular plane perpendicular to the central axis of north and south poles of magnet and all electrons moving in the same direction. The inner electrons of atom keep 360 degree full dimensional spherical shell patrol motion. They delimit the spatial territory of atom by charge repulsion, stabilize atomic boundary and prevent atomic nucleus from collapse. The random distribution hypothesis of electron cloud cannot explain magnetization self consistently. If electrons have no definite motion track and only disperse in the form of probability cloud, there will be no same direction circular stirring motion that can excite cylindrical vortex in fixed direction and macroscopic magnetic poles cannot be generated. Magnetization only reconstructs this group of magnetizable electrons and unifies their orbital plane and rotation direction. Countless micro vortices excited by same direction circular motion of electrons superpose together and finally form macroscopic cylindrical vortex field to generate stable north and south magnetic poles. Demagnetization means this group of electrons restore spherical disordered shell motion again and unified vortex field dissipates and magnetic property disappears. This study revises the vague cognition of traditional physics on microscopic mechanism of magnetization and establishes the original correspondence between electron orbital motion and macroscopic magnetic field.
