Main Question or Discussion Point
Translated from Norwegian high-school physics book:
I wonder how and why does the voltage change on the primary coil when the cookware is removed or boiled over?One of the advantages of an induction stovetop is that it can detect when the cookware is removed from the plate or it boils over. It detects it by changing the voltage in the primary coil underneath the plate. This technique also allows for other functions, such as the cooking plate can adjust so that the food boils so far, or that the plate can turn off automatically when the cookware is removed from the plate.
