Yes, it’s perfectly fine to use cast iron cookware on an induction cooking surface. Cast iron possesses the ferrous magnetic qualities that are necessary for an induction surface to work. I will give one word of caution, however! Cast iron cookware is designed to take a great deal of punishment in the kitchen. That means the exteriors can often become quite rough if they’re not regularly maintained. Be careful not to slide any toughened cast iron around on your induction hobs. That increases the risk of creating scratches.
