1. An aerosol generating apparatus comprising:
a case into which a cigarette including an electromagnetic inductor is insertable;
a heating unit configured to heat the cigarette;
a detector that includes a coil, and measures a current characteristic value of a current flowing through the coil according to predetermined time information; and
a controller that controls operation of the heating unit by comparing the current characteristic value measured by the detector with a predetermined reference current characteristic value,
wherein the reference current characteristic value is set based on at least one current characteristic value measured by the detector.
