Hysterisis loss for a sample of 120kg is 300Jm^-3//cycl e . Frequency of supply is 50cycl e//s . If density of iron is 7500kg//m^3 , find energy loss in 60 minutes.

An iron sample having mass 8*4kg is repeatedly taken over cycles of magnetisation and demagnetisation at a frequency of 50cps . It is found that energy of 3*2xx10^4J is dissipated as heat in the sample in 30 minutes. If the density of iron is 7200kg//m^3 , calculate the value of energy dissipated per unit volume per cycle in the iron sample.
