Electromagnetic oven why stainless steel pot can cook, and aluminum pot on it?
The electromagnetic oven is an electric cooking appliance made by the principle of electromagnetic induction heating. Stainless steel is divided into austenite and ferrite, ferrite with magnetic conductivity, the majority of stainless steel pot for ferrite, electromagnetic oven can be used for cooking, aluminum is non conductive magnetic metal, therefore, can not use electromagnetic oven.
Because of the excessive or excessive resistivity of the material, the cooker of other materials will cause abnormal electromagnetic oven load and start automatic protection, which will not work properly. At the same time, because iron absorbs the magnetic field sufficiently, the shielding effect is also very good, this has reduced many magnetic radiation, therefore the iron pot is more safe than any other material cooking utensil. In addition, iron is a beneficial substance for human health and a necessary element for the long-term intake of the human body.
The electromagnetic oven is through the electronic circuit board part produces alternating magnetic field, when the iron pot is placed at the bottom of the furnace surface, the current pan cutting in the bottom of the pot and the alternating magnetic field generated by the alternating metal parts (i.e., eddy current) eddy making pot free electrons swirl in the bottom of alternating motion of iron materials. The Joule heat current makes the heating pot.
Induction cooker must use iron, special stainless steel or iron baked enamel pan.
