The Blizzard BIH1 Single Zone Induction Hob 3000W method uses electromagnetism to create a magnetic field between the pan. 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. The heat is transferred directly to the pan rather than the whole surface.
