Hysteresis and Eddy Current Loss Theory: Hysteresis Loss: If a magnetic material is magnetized in a strong magnetic field, it retains a considerable portion of magnetism after the magnetic forces has been withdrawn. The phenomenon of lagging of magnetization or induction flux density behind the magnetizing force is known as magnetic hysteresis. Let a core […]
