The NuWave PIC Pro is comprised of a series of magnetic coils. These coils generate magnetic fields that produce a warming reaction in steel and iron based pots and pans. In this way, heat is generated in the cookware and not on the cooktop surface, which is much more energy efficient than traditional gas or electric ranges. Induction cooking is the most eco-friendly way to prepare meals because the method releases no toxins into the environment. Induction cooking emits no flame, so less residual heat is produced in your own kitchen. The cooktop remains cool to the touch where the magnetic surface is not activated.
