The invention provides a coil apparatus () for inductive power transmission, comprising an electromagnetic coil () for emitting and/or picking up an electromagnetic field () on a transmission side () of the coil apparatus (), and comprising a housing wall (), which covers the coil () on the transmission side () and is transmissive to the electromagnetic field (). Furthermore, the coil apparatus () comprises a housing medium (), which is enclosed by the housing wall () in such a way that, when a through-opening () is formed in the housing wall (), the housing medium () passes through the through-opening (). Alternatively, a housing vacuum is provided which is enclosed by the housing wall in such a way that, when a through-opening is formed in the housing wall, atmospheric air () passes through the through-opening. Among further aspects, a vehicle comprising such a coil apparatus and a method for inductive power transmission are provided. The method comprises steps of providing an electromagnetic coil () for emitting and/or picking up an electromagnetic field (), covering the coil () on a transmission side () with a housing wall () which is transmissive to the electromagnetic field (), enclosing a fluid () with an internal pressure which is different than the atmospheric air by the housing wall (), 1100.
