Mondo Knows Facts

Induction hobs heat the pan directly

A magnetic field induces currents in steel, and the surface stays cool An induction hob runs an alternating current through a coil beneath the glass, creating a changing magnetic field. That field induces eddy currents in a ferrous pan, and the metal's resistance turns them into heat, so the pan warms while the hob surface stays comparatively cool. Glass and aluminium pans do not work unless they carry a magnetic base plate. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
