This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It is intended for use by college students who are non-physics majors. The approach is phenomenological and macroscopic. The monograph contains three chapters. Chapter 1 discusses Faraday's experiments on induction, the concept of an electromotive force, generators, motors, and the Betatron. Chapter 2 is concerned with Ampere's circulation law for steady currents and its applications. The propagation of an electromagnetic disturbance is the subject of chapter 3. Each chapter has a number of exercises. (LC)
