Electrolux ICON 36 inch Induction Cooktop

How Induction Cooking Works
Induction cooking uses high frequency magnetic energy to heat the cooking utensil when it is placed over the induction coil. The induction fields have no affect on non magnetic surfaces such as paper, plastic, glass, ceramic, or non ferrous metals like aluminum, copper etc.
An induction cooking system requires two key components to operate.
The first component is the induction coil or element. This coil generates the magnetic induction field needed for induction cooking.
The second key component is the cooking utensil or pan with a bottom constructed of material that will attract a magnet.
If a magnet will not stick to the bottom of the pan it cannot be used for induction cooking.
When the proper type of pan is placed over the induction coil and the coil is energized it generates a field of magnetic waves that cause the bottom of the pan to heat.
Induction cooking is highly efficient since the en ergy created by the induction fields is not wasted by heating the glass and surrounding area of the cooktop surface.
Due to this increased efficiency the contents of the pan are heated more quickly than with gas burners or traditional radiant electric and coil elements.
Since the induction fields heat only into the cooking utensil the surrounding surface remains cooler than with traditional cooktops.
SELECTING PROPER COOKWARE
When selecting a pan to use for induction cooking it is important to know the correct size of the pan in order to determine the proper cooking zone to be used. The size of the magnetic portion of the pan bottom has a direct effect on the cooking performance and efficiency of the cooking zone. Pan design and construction vary widely as can be seen by the examples given below.
The following illustrations show some of the variations found in the construction of pan bottoms.
The overall diameter of this pan is 9 inches if measured at the top portion. The flat magnetic portion of the bottom (shaded in gray) is only 7 inches in diameter. This pan would be considered to be a 7 inch pan and should be used on a cooking zone appropriate for this size.
The bottom of this pan is a non magnetic alloy with an encapsulated inner core of magnetic material. The inner magnetic core is 1 inch smaller than the outer dimension of the flat pan bottom. This pan will have different cooking characteristics than the pan previously motioned. The effective cooking diameter of this pan is 6 inches.
Pan has a bottom of non magnetic alloy with a different shaped encapsulated inner magnetic core. The illustration shows that the core is thinner near the outer perimeter of the pan bottom and increases in thickness as it nears the center of the pan. This type of pan will have different cooking characteristics than a pan with a uniform core thickness.
