Induction Cooking - Jenn-Air A130 R Use And Care Manual

Induction Cooking
Induction cooking is a revolutionary way of cooking.
The physical principle that makes induction cooking possible is not a new one.
For over 50 years, industry has used the induction process to heat-treat or melt
metals.
Experimenting with induction cooking began as early as 1890. However, the
technology necessary to make induction cooking available in the home is a more
recent development.
Induction cooking makes surface cooking faster and easier. The induction
cooktop cartridge also has some built-in design features that provide greater
performance and energy efficiency. For these reasons, it is destined to become a
favored way of surface cooking by anyone who has the opportunity to cook with
induction.
The Induction Process
The cooking process is based on a unique application of electromotive force.
Underneath the glass-ceramic cooktop surface there is a flat coil of wire for each
cooking surface area. Each coil has its own solid state power supply.
When the range surface control know is turned on HI, this solid state circuit con-
verts the electrical current into a high frequency alternating current.
This alternating current flows through the coil and creates an alternating
magnetic field. The intensity of this field can be varied by using the slide control
on the induction cartridge.

When a utensil containing magnetic materials (ferromagnetic elements such as
iron, nickel, cobalt, or various alloys) is brought into the oscillating magnetic
field, the current will flow through the utensil. This is an induced current; hence,
the name induction. Because this current flow is in the opposite direction of the
coil under the glass cooktop, the molecules in the utensil are caused to move
back and forth rapidly. This movement, resistance to electrical flow, causes the
utensil to heat very rapidly. It is the hot utensil that cooks the food not the
electrical heating element or glass-ceramic cooktop as is the case with
conventional electric ranges.
Glass-ceramic does not contain any ferromagnetic materials; it is transparent to
the current. Since it is unaffected by the current, it provides an easy to care for
surface that remains relatively cool during the cooking process.
