I have been using induction for many years and for the most part I have found that it is simple on and off. Either a pan works or it doesn’t. The only time it becomes iffy is when the pan is warped and does not make good contact with the induction hob.

I do seem to recall one pan that seemed that it might work. The heat would come on and then go off and if you moved the pan it might come back on again. I recall that a magnet would barely cling to the bottom of this pan.
