Question: How can I tell if I can use my current pans on induction?
Induction hobs only work with pots and pans that contain ferrous metal in the base. To check if your pans will work, hold a magnet next to the pan base; if it attracts, the pan will work on induction. Another way of checking is to pour a small amount of water into the pan and then place it on the cooking zone. If the display starts flashing, the pan is not compatible.
Full stainless steel, aluminium, copper, terracotta or pyrex don't contain ferrous material, so theoretically they won't work. However most pan manufacturers are now producing pans which are suitable for use on induction cooktops, even if they are made from some of the materials mentioned above. This is because they are incoporating some ferrous material in the base of the pan. Look out for the induction symbol when buying new cookware.
