Hysteresis in Induction Cooking

[Faradae]

Hi all, I was researching into Induction Cooking (using induction plates) recently and chanced upon a few websites that mentioned about hysteresis in Induction Cooking. However I don't really get how does hysteresis have a part to play in Induction Cooking. :/

The area of the hysteresis loop represents the heating power.

The hysteresis is due to the cycle of induced magnetisation of the material of the pan. Each cycle, there is some energy transferred, which heats the pane and contents.
