1. An aerosol-generating device, comprising:
a housing having a chamber configured to receive at least a portion of an aerosol-forming article;
a first helical inductor coil disposed at least partially around the chamber;
a second helical inductor coil disposed at least partially around, or adjacent to, the chamber; and
an elongate susceptor element, in a form of a pin or a blade, configured to be inductively heatable by one or both of the first and the second helical inductor coils to heat at least a portion of an aerosol-forming substrate which is part of the aerosol-forming article, when the aerosol-forming substrate is at least partially received in the chamber.
