This paper presents the first theoretical framework that defines the electric infinitesimal structure model of electromagnetic waves. This model represents the electromagnetic fields by electric field components only. These components have a specific spatial arrangement that is responsible for exerting both the magnetic force and the electric force applied by the electromagnetic waves. There is no existing work that specifies this infinitesimal purely electric structure. Previous work considered electromagnetic waves to be formed by two types of fields, despite the belief that the magnetic field is an electric field in its origin. The model has been built by analyzing the changes in the flow of electric charges producing changing currents. ...
