The Principle of Induction Heating: When you place your cookware on a cooking zone and you turn it on, the electronic circuits in your induction hob produce “induced currents” in the bottom of the cookware which instantly raise cookware’s temperature. Induced currents Induction coil Electronic circuits NZ64F3NM1AB NZ63F3NM1AB 1,250W 2,350W 2,350W 1,250W...
