Question

2) The hysteresis loop of a sample steel-sheet is given for a flux density of Bmax = 1.51. The area
of the loop is found to be 0.9 cm? The scale is such that 1 cm = 10 A/m and 1 cm = 0.8 L Find
the loss in Watt due to hysteresis if 1200 cm of this iron is subjected to an 50 Hz alternating
flux density with peak value 1.5 T.​
