Induction hobs create heat from magnetic energy. This energy is only activated by ferromagnetic metals. Put very simply, you need pots and pans made of metals like stainless steel and cast iron that a magnet would stick to.
Materials like copper, aluminium, or ceramic will not work on induction hobs. The easiest way to test whether a cookware will work on an induction hob is to see if magnets stick to its base. Plus, it’s a good idea that the base be flat as induction energy is only activated by the touching of materials.
Cookware manufacturers have been engraving a coiled spring symbol on the bottom of their products to help consumers recognise induction-safe items. Some products come with an induction plate on the base, despite being non-ferrous themselves.
