Answer / lakshmi

high grade silicon steel. eddy current and hysteresis
losses are depend upon frequency. for high frequency the
losses are also increases. and hysteresis loss are also
depends upon hysteresis coefficient (n). high grade silicon
steel (crgo steel) having low hysteresis coefficient that's
why it is used at high frequency transformer.
