In variations to this embodiment, the heating element 2 may be penetrable by fewer than all of the varying magnetic fields in use. In some such variations, the non-penetrated portion(s) of the heating element 2 may be heated in use by thermal conduction from the penetrated portion(s) of the heating element 2.

In some embodiments, the article 10 may include at least one heating element comprising heating material that is heatable in use by penetration with one or more of the varying magnetic fields to heat the aerosolizable material 12 of the article 10. The heating element(s) of the article 10 would be in thermal contact, and in some embodiments surface contact, with the aerosolizable material 12 of the article 10. For example, a heating element of such an article 10 may be elongate and extend from a first end of the article 10 to an opposite second end of the article 10. The heating element of the article 10 may be tubular or rod-shaped, for example. In some such embodiments, the aerosolizable material may be radially inwards or radially outwards of the tubular heating element of the article 10. In some embodiments, the article 10 may include heating material that is dispersed within the aerosolizable material 12 of the article 10. For example, the article 10 may include a material comprising a mixture of aerosolizable material 12 and elements, wherein each of the elements comprises heating material that is heatable by penetration with a varying magnetic field. Each of the elements may comprise a closed circuit of heating material. Some or each of the elements may be ring-shaped, spherical, or formed from a plurality of discrete strands of heating material, for example.
