1. An aerosol-generating apparatus comprising:
a plurality of chambers configured to accommodate a flavoring material;
a coil antenna;
a rotating body configured to rotate with the plurality of chambers relative to the coil antenna, the rotating body comprising a plurality of teeth that change an inductance of the coil antenna by rotation of the rotating body;
an inductive sensor configured to detect the inductance and identify a rotation amount and a rotation direction of the rotating body based on a change in the inductance; and
a processor configured to identify a chamber in use from among the plurality of chambers, based on the rotation amount and the rotation direction of the rotating body.
