Present book, entitled “College Physics – Vol. III: Electricity and Magnetism”, has been written for B.Sc. (Physics) students of Semester-III of Bangalore University. The prescribed syllabus, mainly describing electricity, magnetism and electromagnetic theory, has been divided into four units. Unit-1 deals with the electric field and potential, network theorems, magnetic field and bassistic galvanometer in the form of three chapters. In Unit-2, source of managetic field and electromagntic induction are discussed in two chapters. Unit-3 presents three chapters on the topics of transient currents, scalar and vector fields and electomagnetic waves. In Unit-4, topics on alternating current and thermoelectricity have been described in the last two chapters of the book.
In order to grasp the basic concepts of physics and to understand the complicacy of the subject matter, we have given a good number of selected and informative solved and unsolved problems in the book. Generally the solved problems have been given in few groups at different places with the relevant theory inside a chapter and each group of problems have been followed by an exercise (set of unsolved problems) for practice. At the end of each chapter of the book, theoretical questions have been arranged in the two heads: (i) Long Answer Questions and (ii) Short Answer Questions.
