When choosing a fry pan with induction, it is indeed necessary to test whether the bottom of the pan has magnetism. This is because the working principle of an induction cooker is to generate eddy currents at the bottom of the cookware through electromagnetic induction, thereby heating the cookware itself to cook food. In order to achieve this process, the bottom of the cookware must be able to respond to the magnetic field generated by the induction cooker, that is, it needs to have a certain degree of magnetic conductivity.
If the bottom of the frying pan lacks magnetism or has weak magnetism, it will not be able to effectively interact with the magnetic field of the induction cooker, resulting in insufficient heat generation or uneven distribution, thereby affecting the cooking effect. Therefore, when choosing a frying pan specifically designed for induction cookers, testing whether its bottom has sufficient magnetism is an important step to ensure compatibility and good cooking performance between the cookware and induction cookers.
Usually, this test can be completed through a simple magnet attraction test, where the magnet is placed near the bottom of the frying pan to observe if it can be effectively attracted. If the magnet can firmly adhere to the bottom of the frying pan, then the frying pan is suitable for use with an induction cooker.
