Abstract
Disclosed is an apparatus for heating smokable material to volatilize at least one component of the smokable material. The apparatus includes a heating zone for receiving at least a portion of an article including smokable material; an outlet for permitting volatilized components of the smokable material to pass from the heating zone towards an exterior of the apparatus when the article is heated in the heating zone in use; a heating element that is heatable by penetration with a varying magnetic field to heat the heating zone, wherein a first section of the heating element is located between a second section of the heating element and the outlet, and wherein the second section of the heating element is heatable in use by thermal conduction from the first section of the heating element; and a magnetic field generator for generating a varying magnetic field that penetrates the first section of the heating element and avoids the second section of the heating element.
