Introduction to Electromagnetic Theory: A Modern Perspective presents a complete account of classic electromagnetism with a modern approach, incorporating real-world scenarios and current technology. The text introduces and then expands upon the four basic types of forces-gravitational, electromagnetic, strong, and weak-using present-day examples and cases. Contents also include electrostatics of charges, magnetostatics, and the Maxwell Equation, as well as the motion of particles in electric and magnetic fields. Written by a leading physicist and teacher, Introduction to Electromagnetic Theory is the most current and comprehensive introduction to the field for advanced undergraduate and graduate physics students.
• Each chapter contains a set of problems for continued study, which vary in degree of difficulty and are intended to supplement or amplify the material presented in the text.
• A review of vector analysis is presented in Chapter 1 to prepare students for the mathematical theory presented throughout the book.
• A broad array of worked examples with detailed explanations aid in students" comprehension and retention of material presented.
Advanced undergraduate and graduate physics students & EE majors.
