At present, the induction cooker is widely used in the kitchen for household and outdoor cooking, but whose first patents date from the early 1900s. It as a civilian cooking utensil was first developed by Westinghouse in 1972 instead of using in industries such as metallurgy and smelting in old days; by the 1980s, the technology of induction cooker gradually matured; now it is very common for cooking dishes, but do you know what the operational principle of an induction cooker is?
let me share with you this principle, at the same time, you can check below picture as reference ：
- The surface of the induction cooker is heat-resistant ceramic glass.
- When powered on, the alternating current passes through the coil under the ceramic glass to generate a magnetic field.
- The magnetic field lines in the magnetic field will generate large eddy currents when they pass through the bottom of the iron pot, stainless steel pot, etc., which quickly heats the bottom of the pot for cooking food.
NOTE: as for the pot, you need to pay attention to below details:
- the pot must be a conductor, which can generate the Electric Current
- it must be with ferromagnetism, which can strengthen the magnetic field, like iron, stainless steel, a cast iron pot, etc. 【Why the raw material of the pot can’t be Copper or Aluminium? As we all know that Copper and Aluminium have thermal conductivity, but this material emits a magnetic field and cannot enhance the magnetic field, so it cannot be used. 】
