A heating apparatus and a heating method are provided. The heating apparatus includes a coil configured to receive AC power to form a magnetic field that inductively heats a workpiece, a spray unit configured to spray cooling fluid including a liquid to the coil in a form of mist at least during a period in which the AC power is supplied to the coil. Alternatively, the spray unit may be configured to spray the cooling fluid in the form of mist to a heating target portion of the workpiece placed in the magnetic field at least during the period in which the AC power is supplied to the coil.

Electric induction heating of the edges of a slab comprising an electrically conductive, non-ferrous material is achieved with a transverse flux induction coil that comprises a pair of coil sections with the slab passing between the coil sections. The coil sections extend transversely beyond the opposing edges of the slab. Magnetic flux concentrators are positioned around regions of the coil sections that are above and below the slab. An electrically conductive compensator is inserted between each of the two opposing extended ends of the coils sections in the vicinity of an edge of the slab. Alternatively only one of the edges of the slab may be inductively heated.

Disclosed is apparatus for heating smokable material to volatilize at least one component of the smokable material. The apparatus comprises 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 comprises smokable material and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material. The magnetic field generator comprises a magnetically permeable core and a coil. The core comprises 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.

An induction cooking heater including an inductor having a number of magnetic field concentration bars located beneath the inductor. The inductor having the magnetic field concentration bars is supported by a polymeric frame. The polymeric frame includes a first support element on which the inductor is wound and a second support element that supports the magnetic field concentration bars. The first support element and the second support element are assembled together through a central ring-shaped zone having a snap engagement. The inductor is wound on an upper surface of the first support element opposite to the second support element.

A fixing device includes a housing, a magnetic flux generation source, a first rotary body, a second rotary body, a first core, a second core, a shaft portion, a magnetic shielding body and an air flow generator. The shaft portion has a hollow cylindrical shape, holds the second core on a peripheral surface and includes an internal space extending in an axial direction inside. The shaft portion serves as a rotary shaft in the rotation of the second core. The air flow generator generates an air flow flowing in the internal space of the shaft portion from one end side toward the other end side in the axial direction.
