Itis noload power loss in a transformer on open ckt.and
equal to sum of eddy currentloss and hysterisis loss.
(copper loss is negligible in this condition)

Answer / priyanka

iron loss is a mixture of magnetisation and eddy current
losses.magnetisation losses occur due to magnetic
reversals.eddy current losses occur due to stray magnetism

Answer / arif latif
