Function of induction coil

Induction coil under vitroceramic glass is used for generating magnetic field. There are
different sizes of coils according to zone diameter (145mm,180mm, 210mm).

Induction coil consists of a magnetic core, a mica sheet for isolation, copper windings, silicon
spacer for air gap, and mica sheet again.

Aluminum sheet which is under the coil is for protecting electronic boards from magnetic
field.
