The short answer to this question is, unfortunately, no. The size of the induction cooker’s burners or hobs varies from manufacturer to manufacturer. For the induction technology to work optimally, the entire cooking area must be covered by a pot or pan that accurately matches its dimensions.
Write down the burner or hob dimensions and keep them handy when buying equipment. Note that the magnetic area on the pan base may be smaller than the pan’s diameter. It is the magnetic area on the base that needs to fit the cooker’s burner. That’s why you need to try them out – you can check whether a pot or pan fits the burner by bringing the pan to the boil. If the product isn’t heating up, or the heat distribution is uneven, you need to look for a different pan. We therefore recommend that you buy one or two products and test them on your cooker before buying the full range.
