Since you are using a magnetic field to heat the pan, the pan MUST be made of something that reacts with a magnetic field.
Stainless steel, cast iron, and even those pots that are steel or iron but clad (such as Le Creuset), work on induction cook tops.
Ceramic, aluminum, copper and glass pots do NOT react to the magnetic field, so they will not heat up. However, if the copper pot is MOSTLY stainless steel and just has a thin layer of copper on its bottom, then it will work.
Actually NORMAL pans, ARE stainless steel ... not the cheap aluminum pans people often buy. Everyone should invest in a decent 5- or 7-layer stainless steel set of pots and pans.
