Induction hobs are quick, safe and efficient, and increasingly becoming a popular choice.
This cooking method uses electromagnetism to create a magnetic field between the pan, which needs to be made from iron, 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 quicker and cheaper to run than other hobs – though more expensive to buy – because the heat is transferred directly to the pan rather than the whole cooking surface, meaning you can touch it without burning yourself.
