Abstract

Experiments show that, there is the electrostatic field around the permanent magnet; since the electromagnetics can not explain this phenomenon, it can be concluded that there are some defects in electromagnetics. This paper makes an analysis of the defects of electromagnetics from fourteen aspects. It is noted that, the basic defect of electromagnetics is that there is no explanation of any inherent causes and physical processes of electromagnetic induction, displacement current, Lorentz force and other surface phenomena. Moreover, it may also lead us to make incorrect inferences in the theoretical analysis of electromagnetics, e.g. the same direction of action and reaction, infinitely high kinematic velocity of magnetic field, etc. It can be seen from analysis of all electromagnetic phenomena that, all the electromagnetic phenomena will be inevitably accompanied by an electron motion; and the electron motion is bound to take effect through an electric field; therefore, the analysis of motion in an electric field is the basis for analysis of all electromagnetic phenomena. This paper proposes seven rules for analysis of motion in an electric field, analyzes the uniform motion and variable motion in an electric field on the basis of such rules, clarifies the inherent causes of Lorentz force, theoretically qualitatively and quantitatively demonstrates why there exists the electrostatic field at some locations around the permanent magnet, and considers that all the magnetic phenomena are resulted from the contraction of electric field in the direction of motion, which is derived from the natural law of constant velocity of light, and therefore all the electromagnetic phenomena is rooted in the constant velocity of light. Through the analysis of variable motion in an electric field, this paper proves the law of displacement current and electromagnetic induction, clarifies the physical processes of such phenomena, deduces the law of total current, explains why electric field strength and magnetic field strength of electromagnetic wave must be in same phase and why a plane wave has the electric and magnetic fields only with a certain length but no source, and considers that neither fast nor slow propagation velocity of electromagnetic wave is good and that the actual velocity of light is the ideal velocity of light.
