Abstract
<jats:p>The tutorial contains the theory of the electromagnetic field and the propagation of electromagnetic waves. Examples of theoretical and practical directions found in electrical engineering, power engineering, electromechanics, automation and measurement technology are considered. The theoretical questions presented in the tutorial will help higher education students understand the processes occurring in electromechanical converters of rolling stock and in the transmission lines of the railway traction power supply system. The tutorial contains examples of solving problems, problems for independent solution, questions for self-control, and basic requirements for knowledge and skills that must be formed in the applicant as a result of studying its sections. Intended for higher education students studying in the specialty G3 Electrical Engineering of all forms of study, as well as in other specialties that involve studying the course of technical electrodynamics.</jats:p>
