This reissue of two classic volumes provides the reader with a comprehensive account at first degree or introductory graduate level of the principles and experimental aspects of electricity and magnetism, together with an elementary account of the underlying atomic theory. The first volume contains what is needed for a first course in electromagnetism, including electrostatics, electric circuits, magnetism, electromagnetic induction, and electromagnetic waves. The second volume covers the electrical and magnetic properties of matter and electronics, including dielectrics, conduction in metals, magnetic materials, semiconductors, superconductors, electronic devices and circuits, and magnetic resonance. SI units are used throughout and there are problems at the end of each chapter.
