A ferromagnetic ring has a uniform cross-sectional area of 2000 mm² and a mean circumference of 1000 mm. A hysteresis loop obtained for the specimen is plotted to scales of 10 mm = 0.1 T and 10 mm = 400A/m and is found to have an area of 104 mm². Determine the hysteresis loss at a frequency of 80 Hz.
