Understanding Magnetic Fields and Circuits

This course covers the fundamental principles of magnetic fields and circuits. It starts with the basic concepts of modeling electrical machines, explaining the correlation between the electrical side and the system's response. The course further explores the generation of magnetic fields in electrical machines, the role of iron in enhancing these fields, and the concept of inductance. It also discusses the impact of changing excitation on the magnetic field and the resulting induced EMF. The course uses the example of a wire loop connected to a DC supply to illustrate these concepts. The course then moves on to the concept of reluctance and inductance in electromagnetic circuits, using the model of a simple wire loop. It also discusses the equivalent electrical circuit for analyzing a magnetic circuit and the importance of inductance in electromagnetic systems.
