Classical Electrodynamics is a comprehensive and classical text for an undergraduate course in electricity and magnetism and graduate course in classical electromagnetism for students majoring in physics and related fields. The goal of the text is threefold. First goal is to provide the basic subject matter as a coherent whole, together in their physical and mathematical description mode; second is to develop and utilize the topics in mathematical physics and third is to present the interactions of relativistic charged particles with electromagnetic fields; thus making this book useful for theoretical physics, experimental nuclear and high-energy physics.
