An induction heating device for heating a metal article includes a support plate with an upper surface for receiving the metal article, and a plurality of induction coils, which are arranged concentrically around an axis and are provided at an underside of the support plate. Each induction coil is connected to and selectively powered by a generator, and at least one temperature probe is disposeable on the metal article during heating in order to monitor and control the heating of the article.

An electronic smoking device (10) is provided including a power supply portion (12) comprising a power supply (18), an atomizer/liquid reservoir portion (14) comprising a liquid reservoir (34) storing a liquid, and an atomizer (26) adapted to atomize the liquid stored in the liquid reservoir (34) when operated by the power supply (18). The atomizer (26) extends away from the liquid reservoir (34) in a first direction (L). The atomizer (26) comprises first atomizer sections (28a, 28b, 28c, 28d), wherein each of the first atomizer sections defines an opening (50a, 50b, 50c, 50d) that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.

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 an article, and a magnetic field generator for generating a varying magnetic field that penetrates the heating zone. The article includes smokable material and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material. The magnetic field generator includes a magnetically permeable core and a coil. The core includes a magnetically permeable first portion and magnetically permeable first and second arms extending from the first portion. The coil is wound around the first portion of the core. The first and second arms of the core are on different sides of the heating zone.

Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.
