Abstract
In an electrically-heated glazing unit including a plurality of collector conductors configured to supply a plurality of heating conductors with an electric current used to heat up the heating conductors and the glazing unit, at least one partial region of the surface of the glazing unit includes an arrangement of parallel heating conductors in which the current flows in opposing directions. The arrangement of the heating conductors in the partial region of the surface is tuned to minimize by mutual compensation or eliminate the magnetic field acting locally within this partial region and perpendicularly to the plane of the glazing unit when the current flows. The operation of an apparatus sensitive to magnetic fields, for example a compass, in the immediate vicinity of the glazing unit thus becomes more reliable.

15. An assembly comprising:
-
an electrically heatable glazing unit; and an apparatus sensitive to magnetic fields installed in the vicinity of the glazing unit; the glazing unit comprising a plurality of collector conductors that supply a plurality of heating conductors with an electric current used to heat up the heating conductors and the glazing unit, wherein the apparatus is situated close to at least one partial region of the surface of the glazing unit, the partial region including an arrangement of parallel heating conductors in which current flows in an opposite direction to that of current in the heating conductors of the part of the glazing unit outside of the partial region, and the arrangement being tuned to minimize by mutual compensation or elimination the magnetic field acting locally within the partial region and perpendicularly to the plane of the glazing unit when the current flows. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
