Introduction To Electromagnetc Theory

The book is intended to emphasize the aspects of electromagnetism which are most important for the modern student as a background both for experimental physics and for the quantum theory of matter and radiation. The emphasis is on physical theory as developed from fundamental empirical laws rather than on mathematics and internal logic. Thus Maxwell’s equations are obtained from the experimental laws of Coulomb Ampere and Faraday instead of postulated initially. The physical concepts come out more clearly in this way and the approach represents the manner in which physical theory evolves. The introduction of electrodynamic potentials and the solution of the wave equation are treated conventionally. Rationalized MKS units are used because the majority of modern reference books and papers are now written in this system of units. I have not concentrated primarily on problem solving the heart of the matter lies in the ideas and their development. Beautiful methods of calculus are used for the simplification of the subject matter. References for further reading are given at the end.
