Aerosol-generating device with internal and external heating arrangement

An aerosol-generating device comprising:

• a housing defining a chamber configured to receive at least a portion of an aerosol-generating article;
• an inductor coil disposed in the housing, wherein the inductor coil is configured to surround the aerosol-generating article when the aerosol-generating article is received in the chamber;
• at least one power supply configured to provide electrical power to the inductor coil;
• and
• control circuitry configured to:
• control a supply of power from the at least one power supply to the inductor coil,
• provide an alternating current to the inductor coil, such that the inductor coil generates an alternating magnetic field to inductively heat a susceptor within the aerosol-generating article,
• provide a direct current to the inductor coil to resistively heat the inductor coil and thereby heat the aerosol-generating article, and
• following activation of the aerosol-generating device, initially provide alternating current to the inductor coil and to subsequently provide direct current to the inductor coil.
