1. A control circuit for use with a device for heating smokable material to volatilize at least one component of said smokable material, the control circuit comprising:
at least a first inductor coil and a second inductor coil, the first inductor coil for generating a first varying magnetic field for heating a first section of a susceptor arrangement and the second inductor coil for generating a second varying magnetic field for heating a second section of the susceptor arrangement,
wherein:
the control circuit is for controlling the first inductor coil and the second inductor coil, wherein, the control circuit is configured so that when one of the first and second coils is actively being driven to generate a varying magnetic field the other of the first and second inductor coils is inactive and wherein the control circuit is configured so that the inactive one of the first and second inductor coils is prevented from carrying a current induced by the active one of the first and second inductor coils sufficient to cause significant heating of a susceptor arrangement.
