ABSTRACT:
A choke coil apparatus for an electromagnetic range comprises an improved ferrite core, so as to prevent an increasing in temperature of the choke coil. The ferrite core in a multiangular bar-shape forms a plurality of ventilation spaces between the choke coil and the ferrite core, thereby air-cooling the choke coil by the air flowing in the ventilation space.
