A New Interpretation of Classical Electromagnetic Theory at the Micro Level
Because Maxwell's classical electromagnetic theory is a macroscopic electromagnetic theory, this paper attempts to establish a new theory of microscopic expression of macroscopic electromagnetic theory to compensate for the shortcomings of macroscopic electromagnetic theory at the micro level. Among them, under the microscopic electromagnetic theory system, the current will be further interpreted as the momentum flow produced by the directed collision between electrons; the charge will be further interpreted as a form of expression of electron motion; the voltage will be further interpreted as the potential difference (energy level difference) of the electron orbit. Finally, this paper successfully developed a new theory of microscopic expression of Maxwell's macroscopic electromagnetic theory by introducing microscopic atomic physics and rigid body mechanics models.
