Silicon steel used in lamination's mainly reduces___________?
Correct answer: A. hysteresis loss
- A. hysteresis loss
- B. eddy current losses
- C. copper losses
- D. all of the above
Explanation
Adding silicon to steel increases its electrical resistivity and reduces hysteresis loss, while the use of thin laminations reduces eddy-current loss. Thus, silicon steel itself mainly targets hysteresis loss.
