A brief theory, problems with solutions and tests on electricity, magnetism and elecromagnetic oscillations. are given. The manual corresponds to the physics course program for technical universities. At the beginning of each chapter, the theoretical foundations, basic definitions and formulas are set out. Many problems of varying degrees of complexity with solutions and tasks for independent solution. are given. Methods of solving tests are outlined and tests are given to test the assimilation of theoretical material. The appendix describes vector analysis, flow calculation methods, and vector rotor. The textbook is intended for students studying in the areas of training "System Analysis and Management" and "Innovation", as well as for university and college teachers, can be useful for applicants preparing for admission to technical universities. ;Grif:Recommended by the UMO for university polytechnic education as a teaching aid for university students studying in the direction of bachelors training "System Analysis and Management" and the direction of bachelors training "Innovation"
