Magnetic circuits are foundational to the design and operation of electrical machines. Devices like transformers, motors, generators, and relays rely on controlled magnetic fields. Understanding how to analyze these circuits is crucial for electrical engineers and students alike.

A magnetic circuit is a closed path through which magnetic flux flows. It is highly analogous to an electrical circuit, which makes learning the concepts intuitive. The Electrical-Magnetic Analogy
