Top view of an induction cooktop. Induction cooking is a cooking process using direct electrical induction heating of cooking vessels, rather than relying on indirect radiation, convection, or thermal conduction. Induction cooking allows high power and very rapid increases in temperature to be achieved: changes in heat settings are ...
An induction cooktop involves the electrical heating of a cooking vessel by magnetic induction instead of by radiation or thermal conduction from an electrical heating element or from a flame. Because inductive heating directly heats the vessel, very rapid increases in temperature can be achieved and changes in heat settings are fast, similar ...
Non-metallic cookware typically can not be used on the stovetop, with the exception of glass-ceramic cookware. Rigid non metallic cookware tends to shatter on sudden cooling or uneven heating, although low expansion materials such as borosilicate glass and glass-ceramics have significant immunity.
A glass-ceramic cooktop (2005) Early electric stoves had resistive heating coils which heated iron hotplates, on top of which the pots were placed. [13] Eventually, composite heating elements were introduced, with the resistive wires encased in hollow metal tubes packed with magnesite. [14] These tubes, arranged in a spiral, support the ...
Also, the image showing an induction coil showing through a fan opening is misleading. True it is an induction coil, but it's a part of the electronic circuitry (probably a mains filter) and not the induction coil used for heating. I'll take some photos next time I open my (broken) hob up for another go at fixing it! Tsh 18:12, 1 March 2007 (UTC)
Observations of an induction hob user: The table top induction hobs that I own both use switching as part of their power control, particularly at low power settings. The switching cycle time is a few seconds in total; that is, the induction is active for a second or more and then inactive for a second or more, repeated indefinitely.
