Resolution

Pans for use on induction hobs come in various types and designs. To work effectively on induction though, at least the base must be made of an iron-based magnetic material. Cast iron is by far the best induction performer but is heavy and expensive, so often, induction pans are made of lighter metal, such as aluminium. These lighter metal pans wouldn’t ordinarily work on induction, so to ensure they can work, they are constructed with composite iron bases.

When buying pots for an induction hob, it is worth doing a simple test that will confirm the quality of the cookware. Put a magnet to the bottom of the pot (it can be a standard fridge magnet), it should "stick" to the pot. The harder it is to detach the magnet from the cookware, the better it will perform during use.

Cause

• There are many types of these “sandwich” type bases, unfortunately not all perform equally or transfer energy (heat) to the main pan material effectively. Sometimes these bases can prove noisy too, as they heat up due to unequal expansion. Noises can vary from squeals to clicking and tapping sounds.
