Explanation of Electromagnetic Wave and Induction by Variation of Electric Fluxline and the Deduction of Magnetism Rooted in Constancy of Light Velocity

摘要

According to superposition principle of electrostatic field, it is considered that electric field of free electron in electric conductor still exists and motions along with free electron. While variable motion of free electron will transmit at light velocity in electric field and form electric wave. This paper analyzed the electric field of electric wave and energy transmitted, explained and deduced law of electromagnetic induction and analyzed Maxwell equations and its physical meaning. In this paper, the author specially made deep analysis on the nature of magnetic field and concluded that constancy of light velocity is the root of magnetism.
