This material can be refined to get the utmost permeability and less coercive force with the help of suitable technique to make it a soft magnetic material. But it produces eddy current loss when subjected to very high flux density due to low resistivity. WebIron losses (hysteresis and eddy current losses) if allowed to take place unchecked, not only reduce the efficiency of electrical equipment but also raise the temperature of the core. Hence these losses should be kept as small as is economically possible. Other Factors Affecting Core Loss: 1. Rivets and Bolts: Laminations must be held together. sccm windows is starting up reboot
