Answer / k.prakashchandra

Nothing, as the flux will be less for the same voltage.Iron
losses increase.

Answer / hanumanth reddy

here two cases will arise.if supply voltage is constant the hysterises loss will decrease and eddy current loss constant.Then total loss will decrease.
if supply voltage is not constant means voltage also increases proportional to the frequency the eddy current losses and hysterises loss increases.
