WebJun 24, 2024 · However, we need an induction-rated pot on the top of the cooker to heat up. Therefore, if the surface of the induction cooker gets hot, that means the reverse of the heat transfer has taken place from the cooking pot back to the surface of the cooker. Although induction cookers heat up fast, the heat is concentrated at the bottom of the cookware. WebNov 15, 2001 · Induction heating's similarity to resistance heating is that conduction is required to heat through the section or part. The only difference is the source of heat and the temperatures of the tool. The induction process heats within the part, and the resistance process heats on the surface of the part. The depth of heating depends on the frequency.

WebInduction heating uses an AC (alternating current) electromagnetic field to generate energy within the part. This causes heating at the surface and subsurface areas of the part due to Joule effect (I2R power losses: where I is current density induced in the part by the electromagnetic induction field and R is the electrical resistance of the part).
