Electromagnetism sets a new standard in physics education. Throughout the Encyclopaedia, the theory is illustrated with real-life applications in modern technology. It also includes detailed worked examples and step-by-step explanations to help readers develop their problem solving strategies and skills and consolidate their undertaking. Electromagnetism provides an ideal preparation for students who plan more advanced studies in electrodynamics as well as those moving into industry or engineering. This Encyclopaedia consist of Ninteen Chapters namely Introduction, Electricity and Magnetism, Electric Potential, Magnetic Forces, Magnetism, Magnetization of Ferromagnetic Materials, Demagnetization, Magnetic Field Indicators, Field Direction and Intensity, Electromagnetic Field Theory, Gravity and Electromagnetism, Magnetic Materials, Properties of Magnetic Materials, Observation of Magnetic Domains, Soft Magnetic Materials, Electromagnetic Radiation, Nuclear Magnetic Resonance, Charged Particle in a Magnetic Field, Electric Power System. Encyclopaedia of Electromagnetism written in a simple and lucid style, and in a manner which is complementary to other texts on electromagnetism will be a valuable addition to the physicist's bookshelf. This Encyclopaedia is for all engineering students in the classrooms and during practical training. It can bridge the gap between the theory of the classroom and the practice in the field. A highly recommended book for all engineering colleges' worldwide, right from first year through final year.
