Abstract
An aerosol-generating system is provided, including: an aerosol-generating device, including a housing, a heating chamber defining a heating zone and being sized to receive at least a portion of an aerosol-forming substrate within the heating zone, an induction element disposed around, or adjacent to, the heating zone, a power supply, and a controller connected to the induction element and configured to provide an alternating electric current to the induction element to generate an alternating magnetic field within the heating zone, the induction element being configured to be controlled to sequentially provide a first alternating magnetic field having a first frequency for a first period of time followed by a second alternating magnetic field having a second frequency for a second period of time.
