Answer / s . v. shinde

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

every motor, generator, transformer consist cover where
winding is fixed, the loss in winding in form of eddy
current or hysteresis is known as iron loss.

Answer / rahul deo maurya

loss by iron winding is iron loss.....
