Microscopic Mechanism of Interaction between Two Parallel Solid Plates at Close Range

Two parallel solid plates without macroscopic magnetism show no observable interaction at ordinary separation, yet when the gap shrinks to the microscopic close range, a weak mutual attraction spontaneously appears at the interface. The existing mainstream theories explain this classic phenomenon through the van der Waals dispersion force, the Casimir vacuum effect, and macroscopic contact adhesion models, but every one of these conventional theories suffers from mechanistic defects. They either consider only instantaneous electric field fluctuations, or rely on the hypothesis of virtual photon exchange in vacuum, or merely give macroscopic phenomenological descriptions, and none of them explains the underlying nature from the intrinsic microscopic magnetic field of the electron. Electrons at the surface of all solid substances undergo spin and orbital motion, and every moving electron produces a local microscopic magnetic field. A macroscopic plate is nonmagnetic because the huge number of electron magnetic fields are disorderly arranged and statistically cancel one another. When two plates approach closely, the separation between surface electrons shrinks greatly, the local electron magnetic fields escape from the macroscopic cancellation effect, and microscopic magnetic adaptation, interlocking and coupling take place, thereby producing a real microscopic mutual attraction. This interaction is a direct close range effect of the electron's own magnetic field and requires no introduction of virtual photon exchange. If the gap continues to shrink to the lattice scale, the coordinated interlocking of a large number of electron magnetic fields produces a very strong binding effect that maintains the stability of the periodic lattice (other factors also influence crystal formation, which is not expanded upon in this paper). By comparing the deficiencies of the conventional theories, this paper establishes a new mechanism of close range electron microscopic magnetic interaction and fully explains the physical nature of close range interaction between parallel solid plates and the stability of crystal structure.
