How induction hobs work

An induction coil is located under each
induction cooking zone. The coil
creates a magnetic field that reacts
directly with the base of the pan and
heats it up. The cooking zone itself is
heated up indirectly by the heat given
off by the pan.
An induction cooking zone only works
when a piece of cookware with a
magnetic base is placed on it (see
"Good to know – Cookware"). Induction
automatically recognises the size of the
cookware.

Noises

When using induction cooking zones,
the following noises can occur in the
cookware, depending on what it is
made of and how it has been
constructed:
Buzzing on the higher power levels.
This will decrease or cease altogether
when the power level is reduced.
If the cookware base is made of layers
of different materials (e.g. in a
sandwiched base), it might emit a
crackling sound.
Whistling might occur if linked cooking
zones (see "Operation – Booster") are
being used at the same time, and the
cookware items also have bases made
of layers of different materials (e.g.
sandwiched base).
You might hear a clicking sound from
the electronic switches, especially at
lower power levels.
A whirring sound, when the cooling fan
comes on. This switches on to protect
the electronic module when the hob is
being used intensively. The cooling fan
may continue to run after the hob has
been switched off.
