how can I tell if my pots and pans are ferrous? I am looking into replacing my hob with an quick, induction type electric hob, but they stipulate that the the cookware must be ferrous. I have decent cookware, but how do I know if it is correct?
If a magnet sticks to it, it's ferrous.

I'd like to give a more elaborate answer, but there isn't anything more to it.
