How Induction Cooking Works

The elements beneath the cooking surface produce a
magnetic field that causes the electrons in the ferrous
metal pan to vibrate and produce heat.
The cooking surface itself does not heat. Heat is
produced in the cooking pan, and cannot be generated
until a pan is placed on the cooking surface.
When the element is activated, the pan begins to heat
immediately and in turn heats the contents of the pan.
Magnetic induction cooking requires the use of cookware
stick, such as iron or steel.
be large enough for the safety sensor to activate an
element.

Cooking Noise

Cookware "noise"
Slight sounds may be produced by different types
of cookware. Heavier pans such as enameled cast
iron produce less noise than a lighter weight multi-ply
stainless steel pan. The size of the pan, and the amount
of contents, can also contribute to the sound level.
When using adjacent elements that are set at certain
power level settings, magnetic fields may interact and
produce a low whistle or intermitted "hum". These
noises can be reduced or eliminated by lowering or
raising the power level settings of one or both of the
will produce less noise.

when cooking with Hi mode. This is normal. The sound
depends on the type of pot being used. Some pots will

reduced, the sound level will go down.
