An analogy to understand the conceptual foundations of electromagnetics at the micro level from the perspective of mechanics

Abstract

This article attempts to provide a new analogy understanding of some conceptual foundations of electromagnetics from the perspective of mechanics to satisfy childhood curiosity. Among them, from the perspective of mechanics, charge can be understood as a form of electron momentum; electric current can be understood as a momentum flow; resistance can be understood as a momentum resistance of electrons; voltage can be interpreted as the potential pressure or energy level difference of the electron orbital potential; the electric field can be understood as a manifestation of the magnetic field of the current element.
