What is a Hysteresis Loop?

If the polarity of H is reversed slowly, very little energy is used. If the polarity of H is reversed rapidly, considerable heat is generated by the molecules bumping into each other in the core, resulting in a high-energy loss known as hysteresis loss. The typical hysteresis curve of a ferromagnetic material is shown in Figure 1. Figure 1.
