9. An inductive heating assembly for generating an aerosol from an aerosol precursor material in an aerosol provision system, the inductive heating assembly comprising:
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,
wherein the susceptor comprises regions of different materials, such that when in use the surface of the susceptor in the regions of the different material are heated to different temperatures by the current flow induced by the drive coil, and
wherein the susceptor has regions of different susceptibility to induced current flow provided by regions of the susceptor having different thicknesses along a direction parallel to a magnetic field generated at the susceptor when the drive coil is in use.
