Households with an induction hob are being encouraged to spend just 25p on a fridge magnet to test whether their cookware is compatible, a move that could save money and prevent frustration during the Christmas cooking season.
Induction hobs operate differently from gas or traditional electric hobs. They generate a magnetic field beneath the glass surface, which produces an electrical current inside the base of a pan. If the pan does not have a magnetic base, the hob cannot generate heat, meaning food cooks unevenly, energy is wasted, and cookware may deteriorate faster.
The test is simple: see if a fridge magnet sticks firmly to the bottom of a pan. According to Ryan Adams, kitchen appliance expert at Miele and director of Ati Harrogate, “If it sticks firmly to the bottom of the pan, it’s likely induction-compatible. However, if the magnet slides off easily, the pan may not have strong enough magnetic properties for efficient heating.” Pans made from cast iron, steel, or some types of stainless steel are usually suitable, while aluminium, glass, and ceramic are not.
The advice comes as UK households are encouraged to switch from gas hobs to electric models in the push towards net zero. Induction hobs are more efficient, quicker to heat, and safer to use, but only when the cookware matches the technology. Adams warns that using the wrong pans can leave users frustrated, and that very high heat can damage surfaces, wearing down non-stick coatings or causing discolouration on stainless steel.
He also highlights the importance of pan size and quality, noting that if pans are too small for the cooking zone, the cooktop may not detect them at all, wasting energy and time. Cheaper cookware can warp under high heat, leading to uneven cooking and the need for replacement sooner, increasing long-term costs. Investing in durable, induction-compatible cookware allows better performance and saves money over time.
