Apparatus for heating smokable material

An apparatus for heating smokable material to volatilize at least one component of the smokable material, the apparatus comprising:

• a heating zone for receiving an article, the article comprising smokable material and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material;
• and
• a magnetic field generator for generating a varying magnetic field that penetrates the heating zone, the magnetic field generator comprising a magnetically permeable core and a coil;
• wherein the core comprises a magnetically permeable first portion and magnetically permeable first and second arms extending from the first portion, the first and second arms defining respective free ends that face each other through the heating zone, wherein the coil is wound around the first portion of the core, and wherein the first and second arms of the core are on different sides of the heating zone,
• wherein the first and second arms of the core are on opposite sides of the heating zone, and
• wherein the core comprises third and fourth arms extending from the first portion, the third and fourth arms defining respective free ends that face each other through the heating zone, and wherein the third and fourth arms of the core are on opposite sides of the heating zone,
• and wherein each of the first, second, third, and fourth arms of the core is elongate in a direction parallel to a longitudinal axis of the heating zone.

• wherein the heating zone has an open first end through which the article is insertable into the heating zone, a second end opposite the first end, and one or more sides connecting the first and second ends;
• wherein the first arm of the core is at the side, or one of the sides, of the heating zone, and the second arm of the core is at the second end of the heating zone,
• and wherein each of the first and second arms of the core is elongate in a direction parallel to a longitudinal axis of the heating zone.

A system, comprising:

• an article comprising smokable material and a heater, wherein the heater comprises heating material that is heatable by penetration with a varying magnetic field to heat the smokable material;
• and
• an apparatus for heating the smokable material to volatilize at least one component of the smokable material, the apparatus comprising:
• a heating zone for receiving the article, and
• a magnetic field generator for generating a varying magnetic field that penetrates the heater when the article is in the heating zone, the magnetic field generator comprising a magnetically permeable core and a coil;
• wherein the core comprises a magnetically permeable first portion and magnetically permeable first and second arms extending from the first portion, the first and second arms defining respective free ends that face each other through the heating zone, wherein the coil is wound around the first portion of the core, and wherein the first and second arms of the core are on different sides of the heating zone, and
• wherein each of the first and second arms of the core is elongate in a direction parallel to a longitudinal axis of the heating zone.
