1. An aerosol generating system comprising:
a cavity configured to accommodate at least a portion of a cigarette;
a first induction coil located around the cavity;
a second induction coil located around the cavity and connected to the first induction coil in parallel;
a battery configured to supply an alternating current to the first induction coil and the second induction coil;
a susceptor configured to be heated by magnetic fields formed by the first induction coil and the second induction coil;
a controller; and
the cigarette,
wherein the first induction coil and the second induction coil have different resonant frequencies,
wherein the cigarette comprises a nicotine transferrer configured to be heated by a first portion of the susceptor corresponding to the first induction coil and a nicotine generator configured to be heated to a lower temperature than the nicotine transferrer by a second portion of the susceptor corresponding to the second induction coil, and
wherein the controller is configured to supply an alternating current of a same frequency to the first induction coil and the second induction coil from the battery when the cigarette is accommodated in the cavity.
