Features: This book reflects the engineering-oriented content system of electromagnetic fields. The entire book is divided into 11 chapters. Chapter 1, Vector Analysis and Field Theory Fundamentals, serves as the mathematical foundation for the entire book. Chapters 2-5 derive the basic equations of electrostatic fields, steady electric fields, steady magnetic fields, and time-varying electromagnetic fields from Coulomb's Law, the Law of Conservation of Charge, Ampere's Law, Faraday's Law, and Maxwell's Displacement Current Hypothesis, and express them as boundary value problems. Chapter 6 discusses the fundamental principles of the image method and extends it to the method of simulated charges. Chapter 7 introduces the finite element method and boundary element method commonly used in engineering based on the concept of weighted residuals. Chapters 8-10 discuss the energy and forces of electromagnetic fields, plane electromagnetic waves, and the principles of circuit parameter calculations. Chapter 11 introduces typical electromagnetic field problems in electrical engineering, including the magnetic field of transformers, the magnetic field of motors, the electric field of insulators, the power frequency electromagnetic environment of three-phase transmission lines, and the capacitance and inductance parameters of three-phase transmission lines. This book was written as part of the Beijing Higher Education Excellent Textbook Project and can be used as a textbook or reference for undergraduate students majoring in electrical engineering in ordinary universities. It can also be referenced by graduate students, teachers, and other scientific and technical personnel in related fields.
