The device includes a housing (110) defining a chamber (120) for receiving at least a portion of the aerosol-generating article, an inductor (200) comprising an inductor coil (210) disposed around at least a portion of the chamber, and a power source (140) connected to the inductor coil and configured to provide a high frequency electric current to the inductor coil such that, in use, the inductor coil generates a fluctuating electromagnetic field to heat the susceptor element and thereby heat the aerosol- forming substrate. The inductor further includes a flux concentrator (230) disposed around the inductor coil and configured to distort the fluctuating electromagnetic field, generated by the inductor coil during use, towards the chamber. The flux concentrator includes a plurality of discrete flux concentrator segments positioned adjacent to one another. An aerosol-generating system comprising such a device, and an inductor assembly for use with such a device are also provided.
