The very purpose of the book is to bridge the gap between the text books of the higher secondary level and the advanced level books on Electrodynamics. The first edition of the book was widely accepted and appreciated by the students and teaching community. This second edition contains a new chapter on Magnetic Field Inside Matter. The solutions of all the exercises are provided in the book itself. The book focuses on basic concepts of electromagnetic theory with stress given on mathematical treatment. The language used in the book is quite lucid. A large number of questions are given at the end of every chapter for ascertaining the clarity of concepts.
