Primarily intended as a textbook for undergraduate students of Physics, this book provides a comprehensive coverage of electricity and magnetism. Organised in 12 chapters, the text is developed based on the vast experience of the author. The book begins with mathematical preliminaries that deal with vector algebra. The text encompasses a wide range of topics, such as electrostatics, current electricity, magnetism and magnetic effect of current. It gives a thorough treatment of electromagnetic induction, varying current, alternating current and their applications. The book lucidly explains heating effect of current, thermoelectricity, theory of magnetism, semiconductors and superconductivity. The topics such as Maxwell’s equations, electromagnetic waves, plasma state of matter, discharge of electricity through gases and magnetohydrodynamics are also elaborately dealt with. The book features a lot of worked-out problems in chapters as well as chapter-end review exercises which will enable students to get a more in-depth understanding of key concepts.

The first part of this state-of-the-art book conveys the fundamentals of magnetism for atoms and bulk-like solid-state systems, providing a basis for understanding new phenomena which exclusively occur in low-dimensional systems as the giant magneto resistance. This wide field is discussed in the second part. Suitable for graduate students in physical and materials sciences, the book includes numerous examples, exercises, and references.

This book is a very comprehensive textbook covering in great depth all the electricity and magnetism. The 2nd edition includes new and revised figures and exercises in many of the chapters, and the number of problems and exercises for the student is increased. In the 1st edition, emphasis much was made of superconductivity, and this methodology will be continued in the new edition by strengthening of the E-B analogy. Many of the new exercises and problems are associated with the E-B analogy, which enables those teaching from the book to select suitable teaching methods depending on the student’s ability and courses taken, whether physics, astrophysics, or engineering. Changes in the chapters include a detailed discussion of the equivector-potential surface and its correspondence between electricity and magnetism. The shortcomings of using the magnetic scalar potential are also explained. The zero resistivity in a magnetic material showing perfect diamagnetism can be easily proved. This textbook is an ideal text for students, who are competent in calculus and are taking physics, astrophysics, or engineering at degree level. It is also useful as a reference book for the professional scientist.
