This textbook offers a rigorous and coherent exploration of electromagnetism, crafted for advanced undergraduate and graduate students, as well as researchers in the physical sciences and engineering. Emphasizing conceptual clarity and analytical depth, it presents a systematic treatment of electromagnetic theory that balances mathematical precision with physical insight. The book is designed not only to convey foundational principles but also to cultivate intellectual curiosity and promote independent inquiry. Through carefully curated problems, reflective questions, and project-based activities, readers are encouraged to engage critically with the material, draw connections across topics, and explore the broader implications of electromagnetic phenomena. Whether the readers aim is to consolidate a concise yet comprehensive understanding of classical electromagnetism or to investigate the quantization of the electromagnetic field, this book provides a thoughtful and intellectually stimulating guide to one of the most fundamental pillars of modern physics.
