The Mechanism of North South Pole Formation for Concentric Vortex Magnetic Field

Charge originates from the spatial disturbance caused by gamma photons inside elementary particles such as protons and electrons. Once charge moves, it excites magnetic field, and the original form of magnetic field is concentric vortex magnetic field. The concentric vortex itself carries north south pole orientation, and its north south pole points along the tangent direction of the vortex. The classical Oersted experiment has long confirmed that the magnetic field around an energized straight wire can deflect a small magnetic needle. The magnetic needle orients along the tangent of vortex. This proves that the concentric vortex generated by moving charge carries north south pole along tangent direction, yet the polar effect distributes along the circular ring and the acting force is scattered and weak. Under alternating current working condition, electrons inside the wire do not move forward continuously in one single direction, but vibrate back and forth at the frequency of 50 hertz. Inside a spiral coil, massive concentric vortices carry out vector superposition in the same direction. Vortex components inside the coil keep superposing towards the same direction, magnetic field is greatly strengthened. Outside the coil, superposition in the same direction also occurs and magnetic field is also enhanced, but the field intensity is far lower than that inside the coil. At atomic level, outer free electrons of atoms mainly participate in magnetization, inner electrons stay stable and generally cannot be polarized by external field. Outer free electrons revolving around atomic nucleus also generate concentric vortex magnetic field. Inside ordinary substances, the revolution directions of outer free electrons of atoms are disordered, magnetic fields offset each other and the material shows no magnetism. Magnetization process can unify and align the revolution orientation of outer free electrons of massive atoms. Countless atomic vortex magnetic fields superpose towards the same direction and finally form stable macroscopic north south poles of permanent magnets. The fundamental property of vortex magnetic field determines that magnetic monopole does not exist in universe. Magnetic flux and magnetic line of force seen in daily use are only simplified expressions, and the real physical form of magnetic field is vortex structure. Combining existing Oersted observation facts, this paper also proposes that precise experiments can be further designed to accurately measure the tangent direction pole feature of concentric vortex. Starting from energized wire, solenoid and extending to atomic permanent magnet mechanism, this paper fully interprets the internal unified relation of magnetic phenomena.
