What will be the area of B-H curve for this specimen




Calculate the loss of energy caused by hysteresis in one hour in 50 kg of if the peak flux density reached is 1.3 T (Wb/m2)and the frequency is 25 Hz. Assume steinmetz coefficient as 628 J/m3 and density of iron as 7.8 x 103kg/m3. What will be the area of B-H curve for this specimen if 1 cm = 12.5 AT/m and 1cm = 0.1 T (Wb/m2 )?
