Abstract
An inductive heating assembly for generating an aerosol from an aerosol precursor material in an aerosol provision system, the inductive heating assembly including: a susceptor; and a drive coil arranged to induce current flow in the susceptor to heat the susceptor and vaporize aerosol precursor material in proximity with a surface of the susceptor, and wherein the susceptor includes regions of different susceptibility to induced current flow from the drive coil, such that when in use the surface of the susceptor in the regions of different susceptibility are heated to different temperatures by the current flow induced by the drive coil.
