Magnetic hysteresis reflects the change in the magnetization, M, vs. applied field, H, when the applied field is increased then decreased in a cyclic fashion. The area between the M vs. H curves for increasing and decreasing H is related to the energy needed to take the material through the cycle. Use Simpson's rule on the M vs. H behavior listed in the table to calculate the area between the curves for the different directions of change of H.
A) 0.210
B) 0.123
C) 0.083
D) 0.165
