induktionskomfur

An induktionskomfur, also known as an induction hob or induction cooker, is a type of electric stove that uses electromagnetic induction to heat cookware. Unlike traditional electric stoves that heat a surface element and then transfer that heat to the pot, induction hobs directly heat the pot itself. This is achieved by placing a coil of copper wire beneath the ceramic glass surface. When an electric current is passed through the coil, it generates a rapidly alternating magnetic field. If a ferromagnetic cooking vessel, such as cast iron or certain types of stainless steel, is placed on the hob, this magnetic field induces electrical currents within the base of the pot. These induced currents cause the pot's molecules to vibrate rapidly, generating heat.

The primary advantage of an induktionskomfur is its efficiency and speed. Because the heat is generated directly in the cookware, very little energy is lost to the surrounding air or the hob's surface. This results in faster cooking times and lower energy consumption compared to other types of stovetops. Induction hobs are also highly responsive, meaning the temperature can be adjusted almost instantaneously, similar to gas stoves. They are generally safer as the hob surface itself does not get as hot as conventional electric elements; it only heats up from the residual heat of the cookware. However, induction cooking requires specific types of cookware that are magnetic. Cookware made of aluminum, copper, or glass will not work unless they have a magnetic base.
