## Abstract

A heating device, its use and a kit for making it are described. The device comprises an induction element, an induced element, and a first elemental dielectric element located between the inductive element and the induced element. The effect of a metal alloy containing a first metal or a mixture of metals in a proportion of 90% and 99.99% by weight to the total weight and to a second metal or a second mixture of metals in a percentage between 0.01% and 10% by weight to the total weight. The first metal is an amagnetic metal, for example diamagnetic or paramagnetic or antiferromagnetic metal, or the first mixture of metals is a magnetic and/or can be understood to include non-magnetic metals. The second metal is a ferromagnetic/ferrimagnetic metal, or the second mixture of metals exclusively including ferromagnetic or ferrimagnetic metals. Alternatively, it is possible to use electrically conductive engineering plastics.
