How an induction hob works
Induction hobs are an increasingly popular choice: no surprise as they are quick and efficient hobs for cooking.
The induction hob cooking method uses electromagnetism to create a magnetic field between the pan, which needs to have a high iron content, and a coil beneath the glass top. Electricity is passed through a copper coil magnet within the induction hob, creating electromagnetic energy. The energy passes through the cooktop directly to the iron-based pan, producing - or inducing - a current which in turn releases heat.
Induction hobs are a quick and efficient way of heating food
Induction hobs are quicker and cheaper to run than other hobs – though often more expensive to buy – because the heat is transferred directly to the pan rather than the whole cooking surface. This means you can touch the cooking surface without burning yourself - but do remember that heat will transfer from warm contents in the pan onto the hob surface, therefore warming it up.

Induction hob pans
You'll need to use 'ferrous pans' - in other words, pans that contain iron - on an induction hob.
As a general rule of thumb, if a magnet sticks to your pots and pans, they will work on an induction hob.
Pans compatible with induction hobs are widely available in kitchenware stores. If your current pans won't work on an induction hob, bear in mind the extra expense of buying a new set.
Getting an induction hob installed
You’ll need to get an electrician to install your induction hob for you. Speak to the store you're buying the product from to see if an installation service is available as part of its delivery package. If you're getting your induction hob as part of a new fitted kitchen, check if it will be installed as part of the fitting service.
