Goal(s)

Physics knowledge of materials behaviors is given. It covers soft and hard magnetic materials and their applications to electro-technical power systems.
Energy conversion, power flow in electrical and electromechanical systems (motors, generators, sensors, power electronic devices) are so presented. The main aims are to improve skill of students for FEM simulation of electromagnetic devices.
