The induction stove is used in a method of directly applying heat as a heating coil by supplying electrical energy, or indirectly heating the induction coil using an electromagnetic induction coil.

The electromagnetic induction method using the electromagnetic induction coil is a method in which the conductor container is heated by the eddy current generated when the magnetic force line generated from the coil is transmitted to the conductor container.

In the case of the electromagnetic induction method, the electromagnetic induction method is preferred because heat is generated in the entire conductor container, whereas in the heating method through the heating coil, heat is applied only to the lower portion of the container.

In the case of the induction range, high-temperature heat is generated from the heating coil as well as the cooking vessel heated by the electromagnetic induction method.
