## Electricity and MagnetismFor 40 years Edward M. Purcell's classic textbook has introduced students to the wonders of electricity and magnetism. With profound physical insight, Purcell covers all the standard introductory topics, such as electrostatics, magnetism, circuits, electromagnetic waves, and electric and magnetic fields in matter. Taking a non-traditional approach, the textbook focuses on fundamental questions from different frames of reference. Mathematical concepts are introduced in parallel with the physics topics at hand, making the motivations clear. Macroscopic phenomena are derived rigorously from microscopic phenomena. With hundreds of illustrations and over 300 end-of-chapter problems, this textbook is widely considered the best undergraduate textbook on electricity and magnetism ever written.
