A majority of electric burners depend on coils. Coils can be either placed under or above a glass or cast-iron surface. This allows electricity to circulate through the coils and heats the pot. Cast iron burners perform in the same fashion as coil-burners, except they are made out of solid metal. An electric burner with a glass top heats up and transfers to the glass. Once the desired temperature is reached, it turns on and off. Differently, an induction stove works by creating magnet energy, which is transferred through the pane to warm the pot.
