In some embodiments, the controller 133 is operable to cause heating of a first section of the aerosolizable material 12 before heating of a second section of the aerosolizable material 12. That is, the controller 133 may be operable to cause a varying electrical current to pass through one or both of the coils 31, 32 of a first of the induction coil arrangements 132 to initiate volatilization of at least one component of a first section 12a of the aerosolizable material 12 adjacent the first induction coil arrangement and formation of an aerosol therein, before causing a varying electrical current to pass through one or both of the coils 31, 32 of a second of the induction coil arrangements 132 to initiate volatilization of at least one component of a second section 12b of the aerosolizable material 12 adjacent the second induction coil arrangement 132 and formation of an aerosol therein. Accordingly, there may be provided progressive heating of the aerosolizable material 12 of the article 10 over time.
