In this new edition of the standard undergraduate textbook on electricity and magnetism, David Griffiths provides expanded discussions on topics such as the nature of field lines, the crystal ambiguity, eddy currents, and the Thomson kink model. Ideal for junior and senior undergraduate students from physics and electrical engineering, the book now includes many new examples and problems, including numerical applications (in Mathematica) to reflect the increasing importance of computational techniques in contemporary physics. Many figures have been redrawn, while updated references to recent research articles not only emphasize that new discoveries are constantly made in this field, but also help to expand readers' understanding of the topic and of its importance in current physics research.
