1. A heating device comprising:an induction element,
an induced element, and
a first dielectric element placed between the induction element and the induced element,
where the induced element comprises a metal alloy containing a first metal, or a first mixture of metals, in a percentage in the range 90%-99.99% by weight to the total weight and containing a second metal, or a second mixture of metals, in a percentage in the range 0.01%-10% by weight to the total weight;
characterized in that the first metal is an amagnetic metal, or in that the first mixture of metals is amagnetic or exclusively comprises non-magnetic metals, and
in that the second metal is a ferromagnetic or ferrimagnetic metal, or in that the second mixture of metals is magnetic or exclusively comprises ferromagnetic or ferrimagnetic metals.
