An electric stove, electric cooker or electric range is a stove with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solid-fuel stoves whic
An electric stove, shown here from the European market, uses electricity to provide heat.
Drawings submitted on 29 November 1905 when David Curle Smith obtained an Australian patent (No. 4699/05) for his "electric cooking stove", also known as "The Kalgoorlie Stove".

Induction cooking is a cooking process using direct electrical induction heating of cookware, rather than relying on flames or heating elements. Induction cooking allows high power and very rapid incr

…surface remains cool. These cooktops have a smooth surface and are thus easier to clean, but are markedly more expensive. A third technology is the induction stove, which also has a smooth glass-ceramic surface. Only ferromagnetic cookware works with induction stoves, which heat by dint of electromagnetic induction…

An early induction cooker patent from 1909 illustrates the principle. Current in the coil of wire S induces a magnetic field in the magnetic core M. The magnetic field passes through the bottom of the pot A, inducing eddy currents within it. Unlike this concept, a modern cooking surface uses electronically generated high-frequency current.
Inside view of an induction cooker: the large copper coil forms the magnetic field, a cooling fan is visible below it, and power supply and line filter surround the coil. In the centre of the coil is a temperature sensor, covered in white thermal grease.
Inductive cooking's heat is produced almost entirely in the cookware's material, rather than in the cooktop or any material in-between (such as the newspaper in this demo).
