Dependence of Electrodynamics on the Models of the Electromagnetic Medium

Abstract

This article traces the influence of physical models of the electromagnetic medium on electrodynamics. The connection between the ability of the electrodynamic equations to describe the processes under study and the adequacy of the model of the electromagnetic medium used in their derivation to the known data is shown. It is revealed that the assumption of the absence of the existence of the electromagnetic medium leads to certain methodological difficulties in deriving the electrodynamic equations. The paper highlights the main milestones in the evolution of the physical model of electromagnetic medium. As a rule, the existence of electromagnetic medium in physics has been denied up to the present time due to the lack of its consistent model. A new physical model of the electromagnetic medium is developed and based on it a system of electrodynamic equations is derived that agree with the known data of physical experiments and astronomical observations. On the basis of the proposed physical model, a mathematical description of the method of detecting the electromagnetic medium is obtained. The developed physical model made it possible not only to explain the data of known electromagnetic phenomena and experiments, but also to propose the Galilean relativity principle within the framework of classical mechanics. Possible consequences of detection of the electromagnetic medium are discussed.
