2.2 - PAN DETECTION SYSTEM
The circuit that generates the magnetic field also checks the impedance of the "load" (i.e. the pan). The
difference in impedance between one pan and another depends on the magnetic properties of the metal and
the dimensions of the pan. A pan made in non-magnetic metal (e.g. aluminium) will not be detected.
The minimum diameter of the pan is indicated for each hotplate, depending on its power and diameter.
2.3 - TYPES OF PANS FOR MAGNETIC INDUCTION COOKING
As described above, magnetic induction hobs require the use of special pans made using magnetic material
which creates an impedance that is higher then the minimum required for the cooking zone on which the pan
is placed.
If the pan is not of the correct type, the system will not detect the presence of the pan and will therefore not
function.
Fig. 3 illustrates an example of a pan specially built for use with magnetic induction hobs. The table below
shows the various materials used.

2.3.1 - HOW TO CHECK WHETHER A PAN IS SUITABLE
- Introduce a small quantity of water into the pan, set the hotplate to level 9 and check whether the
water is heated rapidly.
- Use a small magnet to check whether the pan is magnetic.
N.B.
Certain types of pan may produce noise when used on magnetic induction hobs. This noise is not a
sign of a malfunction in the hob, and in no way affects its correct operation.
N.B.
The bottom of the pan must be as
thick
and as
flat
as possible.
