Classical electrodynamics is a cornerstone of physics and engineering education. Its principles underpin a vast array of technologies and serve as a foundation for advanced topics such as quantum mechanics, statistical physics, and relativity.

This textbook aims to provide a unified treatment of classical electrodynamics and its applications, incorporating mathematical rigour, clear explanations of symmetry and invariance principles, and concrete connections to modern technologies. Each chapter is enriched with illustrations of contemporary applications, from the working principles of touchscreens, particle accelerators, 3D glasses and liquid crystal displays to medical imaging technologies like MRI. These real-world examples ground the theory in practical contexts and also inspire readers to see the relevance of electromagnetism in everyday life. Additionally, brief notes are provided on the most influential scientists who shaped the laws and principles discussed. Numerous fully solved exercises are available at the end of each chapter to deepen the knowledge. An ideal companion for any undergraduate and graduate course on this subject.
