Is the cooker inner pot a regular magnet?
Should be austenitic stainless steel, not magnetic, so the induction cooker does not induction, can not work. This is also the reason why not all pots can use an induction cooker.
Where is a circular common magnet, special is the spring magnet below, the spring is elastic at normal temperature, when the temperature reaches 105 degrees, will lose elasticity, automatically disconnect the heating circuit, automatically enter the state of insulation.
It is not an ordinary magnet, because its "Curie point" is different, and the Curie point is that it loses its magnetism when it reaches a certain temperature. The Curie point of the magnet in a rice cooker is 105 degrees. At this temperature, it loses its magnetism. Under the action of spring. It will jump, disconnect the switch to switch the heating insulation.
