Magnetic Circuits

Magnetic circuits are fundamental elements in many electrical and electronic devices, including transformers, motors, generators, and power converters. Understanding magnetic circuits is essential for a comprehensive grasp of these devices and their applications. This article provides an overview of magnetic circuits, why one might want to learn about them, and how online courses can facilitate the learning process.

What is a Magnetic Circuit?

A magnetic circuit is an analogy to an electric circuit in which magnetic flux flows through a path instead of electric current. It consists of a source of magnetomotive force (MMF), a magnetic path, and a magnetic load. The MMF is generated by a current-carrying conductor or a permanent magnet and drives the magnetic flux through the magnetic path. The magnetic path provides a path for the magnetic flux to flow and can include materials with different magnetic properties, such as iron, steel, or air. The magnetic load represents the impedance to the magnetic flux and can be devices like motors, generators, or transformers.
