The Magnetic Circuit, Vol. 1 (Classic Reprint)

Master the fundamentals of electromagnetism with a practical engineering focus.

The Magnetic Circuit, a classic text by V. Karapetoff, explains core concepts using the ampere–ohm system of units and a clear, engineering‑minded approach. It introduces magnetic flux, magnetomotive force, reluctance, and permeance, then builds up to more complex topics as they apply to real machines and systems. This edition emphasizes practical understanding over theory alone. It guides readers from basic relations to the behavior of magnetic circuits in iron, hysteresis and eddy currents, induced electromotive force, and the energy stored in electromagnetic fields. The material is anchored in engineering practice, with numerous illustrations and hundreds of numerical problems that illustrate how theory translates to design and analysis. The text explains how to treat magnetic circuits similarly to electrical circuits, and how to apply the ideas to transformers, motors, and other electrical machinery. It is designed to be used in lectures, recitations, and computing sessions, with chapters that can be studied in a flexible sequence.

• Learn the fundamental relations between flux, magnetomotive force, reluctance, and permeance
• Study magnetic effects in iron, including magnetization, saturation, and core losses
• Explore induced electromotive force in electrical machinery and energy stored in magnetic fields
• Apply concepts to transformers, motors, and transmission lines through practical problems

Ideal for students and professionals in electrical engineering who want a solid, applied understanding of magnetic circuits and their role in machines and power systems. The book supports independent study and classroom use, with a hands‑on emphasis on problem solving.
