Aerosol generating device with inductor

An inductor assembly for an electrically operated aerosol-generating device, the inductor assembly defining a chamber configured to receive at least a portion of an aerosol-generating article and comprising:

• an inductor coil disposed around at least a portion of the chamber;
• and
• a flux concentrator disposed around the inductor coil and configured to distort a fluctuating electromagnetic field generated by the inductor coil toward the chamber,
• wherein the flux concentrator comprises a plurality of discrete flux concentrator segments positioned adjacent to one another.

An electrically operated aerosol-generating device for heating an aerosol-generating article including an aerosol-forming substrate by heating a susceptor element positioned to heat the aerosol-forming substrate, the device comprising:

• a device housing defining a chamber configured to receive at least a portion of the aerosol-generating article;
• an inductor comprising an inductor coil disposed around at least a portion of the chamber;
• and
• a power source connected to the inductor coil and configured to provide a high-frequency electric current to the inductor coil such that the inductor coil generates a fluctuating electromagnetic field to heat the susceptor element and thereby heat the aerosol-forming substrate,
• wherein the inductor further comprises a flux concentrator disposed around the inductor coil and configured to distort the fluctuating electromagnetic field toward the chamber, and
• wherein the inductor further comprises a cushioning element positioned between the flux concentrator and the device housing.
