1.3 Hysteresis Loss
Hysteresis loss is the result of cycling the magnetic material along its
B-H curve (as shown in figure 3); it represents the energy taken as the
applied voltage aligns magnetic dipoles first in one direction and then in
The loss increases with the area of the B-H curve enclosed.
As the material is driven closer to saturation, both the area within the
curve, and the corresponding energy loss each cycle, increase
