1.	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.
Answer» Here, `m=120kg` Hysterisis loss `=300Jm^-3//cycl e`. Frequency `=50c//s` Density of iron `=7500kg//m^3` Total time =`60 mins=60xx60s` Volume of specimen `=(mass)/(density)=(120)/(7500)m^3` Loss of Loss of `en ergy//cycl e=300xx(120)/(7500)=360/75` Loss of `en ergy//sec=360/75xx50` Total loss of energy `=360/75xx50xx60xx60` `=240xx3600` `=86*4xx10^4J`
