1. An apparatus for generating an aerosol by an induction heating method, the apparatus comprising:
a battery supplying a direct current power to the device;
at least one susceptor formed in an elongated structure extending in a longitudinal direction of a cigarette to be accommodated in the apparatus, and arranged to be inserted into the cigarette to heat the cigarette;
an ejector including an accommodating space for accommodating the cigarette, and an opening formed at one end of the accommodating space so that the cigarette is inserted in the accommodating space, wherein the at least one susceptor is arranged at another end of the accommodating space opposite to the one end of the accommodating space, and the ejector is detachably coupled to the apparatus together with the at least one susceptor;
a coil arranged to surround the ejector along the longitudinal direction when the ejector is coupled to the apparatus, and configured to apply an alternating magnetic field to the at least one susceptor so that the at least one susceptor generates heat; and
a controller that controls a power supplied to the coil by controlling the direct current power supplied from the battery based on the temperature of the susceptor.
