There are no evidence to say that Induction cooking is bad for health. They are safe. It is true that an induction cooktop uses electromagnetic current thus it is ideal that you use magnetic cookware. There is also the fact that due to the induction nature of the cooktops, they MAY emit a low frequency radiation that is much like at the microwave frequency. This might bring up the question of how harmful electromagnetic fields and radiation emitting cooktops are but in reality, an induction cooktop is completely safe to use.
