Commercial Induction Ranges from CookTek
Induction hobs produce medium-frequency magnetic fields that generate electric currents in ferromagnetic pans. (There are special pans made for induction hobs, but, in general, if a magnet sticks to a pan it will work for induction cooking.) The resistance of the metal in these pans to the current creates near instantaneous heat on their surface, but only the pan and the food are heated while the surrounding air and stove surface remain relatively cool, and since there is no flame, there are no combustion gases.
