Claim 0:
1. An aerosol-generating device using induction heating, comprising:
a plurality of coils having different numbers of windings and configured to generate alternating magnetic fields based on an alternating current;
a susceptor configured to generate an aerosol by heating adjacent aerosol-generating substrates using heat generated through the alternating magnetic fields generated from the plurality of coils; and
a controller,
wherein the plurality of coils comprises a first coil corresponding to a first portion of the susceptor and a second coil corresponding to a second portion of the susceptor, and
wherein the controller is configured to control the alternating current to be supplied to the first coil and the second coil, such that the first portion and the second portion of the susceptor are heated differentially by the alternating current.
