1. An aerosol-generating device for generating an aerosol by inductively heating an aerosol-forming substrate, the aerosol-generating device comprising:
a device housing comprising a cavity configured to removably receive at least a portion of the aerosol-forming substrate to be heated;
an inductive heating arrangement comprising an induction coil configured to generate an alternating magnetic field within the cavity in a range between 500 kHz to 30 MHZ,
wherein the induction coil is formed by a plurality of turns of a composite cable arranged around at least a portion of the cavity,
wherein the composite cable comprises a first side facing inward towards the cavity, a second side opposite to the first side facing outward away from the cavity, and an electrical conductor embedded at least partially in an insulating conductor encasement,
wherein the electrical conductor comprises a plurality of non-insulated wires in electrical contact with each other, and
wherein the electrical conductor is arranged asymmetrically with regard to an outer cross-section of the composite cable so as to be closer to the first side of the composite cable than to the second side of the composite cable.
