Magnetic Energy: Saturation and Coenergy

This lecture covers the calculation of magnetic energy in the presence of saturation, introducing the concept of magnetic coenergy for force calculations in saturated cases. The instructor explains the process step by step, highlighting the importance of considering the totalized flux and conducting numerical calculations due to non-linearity. The relationship between current, magnetic potential, and totalized flux is explored, leading to the representation of current and flux in terms of magnetic field strength and area. The lecture concludes by discussing the significance of magnetic coenergy in electromechanical conversion processes.
