This is an introductory textbook on electromagnetic fields suitable for undergraduate engineering courses in electrical engineering. It adopts a straightforward approach of presenting theoretical concepts in brief and using several worked-out examples of varied kinds to provide a further understanding of concepts. The material covered in the book broadly aims to develop formulations associated with the analysis of electrostatic, static magnetic and time-varying electromagnetic fields. A review of vector calculus, included as an appendix, provides the necessary mathematical background for understanding the treatment.
