This is a textbook for undergraduate students pursuing an advanced degree in physics. Written according to the UGC Model Curriculum, it covers Courses P4 (Electricity and Magnetism) and P10 (Electrodynamics, Electromagnetic Waves and Relativity). The book is divided into 6 parts. The first 5 parts deal with the physics and the last part is devoted to Indian Contributions in Physics (which is also a part of the UGC Model Curriculum). In all chapters, derivations are worked out in detail to help the average student. Tutorials are included in almost all the chapters, as prescribed by the Curriculum. A concurrent course in Vector Calculus is required.
