This Book is on the basics of electromagnetism needed for further understanding of advanced electromagnetics and its applications in electrical engineering. Taking into account a number of contributions in this field, our material is given in a concise manner to remind the Readers only the main electromagnetic equations. Among them are those given for static electricity, stationary magnetism, and the Maxwell and wave equations, electromagnetism, electrical engineering, static electric and magnetic fields, electrostatics, magnetostatics, time varying fields, propagating electromagnetic fields, electromagnetic waves. the boundary conditions and boundary value problems are considered and the reflection of plane waves is studied as an example of these problems.
