A) both hysteresis loss and eddy current loss in the core will increase
B) hysteresis loss will increase but eddy current loss will decrease
C) hysteresis loss will decrease but eddy current loss will increase
D) hysteresis loss will decrease but eddy current loss will remain unchanged




Answer : D) hysteresis loss will decrease but eddy current loss will remain unchanged
