There is no any doubt that the undergraduate student in electrical engineering needs broad and deep understanding for the principles of electric and magnetic fields as background for the rapidly developing areas referred to as electromagnetic energy conversion engineering by some and by others. Thus, in addition to the general aspects of electromagnetic fields, discussion of the sources and points of development forces and torques in such fields, the general features of energy storage, energy flow, energy transfer, energy conversion all of those require added emphasis. The text material of this book divides itself into nine Chapters: The first for vector analysis, the next four for electro-static field, the next two for the steady magnetic field arising from dc current, the eighth for time varying fields, Maxwell's equations and wave equations and the latter for energy, force and torque in electromechanical transducers. Thus, this book, covers approximately, all the introductory phase of the needs of the electrical engineering student with very simple manner. Thus, this book has been written to meet the introductory phase of the needs of the electrical engineering student.
