The difference between the advantages and disadvantages cooker and electric furnaces

In use, the appliance easier to use.

Furnaces resistance wire is energized after the electrical energy into heat, radiation is small can be ignored, but more cost electricity.

Induction is part generated by the electronic circuit board composed of alternating magnetic field, when containing at iron pot with bottom placed stovetop, cookware namely cutting the alternating magnetic field lines in the pot with the bottom of the metal part of the alternating current (ie turbulence) iron cookware vortex make high-speed random motion of molecules, molecules collide with each other, friction generated heat (hence: cooker cooking pot from the heat source at the bottom of the cooker itself rather than heat transfer to the pot, the heat efficiency than the efficiency of all cookware They were up nearly 1 times) to make the appliance itself own high-speed heating for heating and cooking food, so as to achieve the purpose of cooking. Heating up fast, high thermal efficiency, no fire, no smoke, no harmful gases, the surrounding environment does not produce heat radiation, small size, good safety and aesthetic appearance, etc., can perform most tasks home cooking. Thus, in some countries the cooker more popular, people rated as the "god of cooking" and "green stove."

But as said before, due to the different heat principle, relatively speaking, induction cooker radiation slightly larger point. But most ordinary household use electric heaters basically no radiation, but a high-frequency electric furnace radiation great.
