This is a essential part of the tokamak with the purpose to create toroidal electric field $E_t$ to breakdown neutral gas into plasma and consequently heat it. \GWidf{0.5\tw}{Tokamak/Transformer/IronTransformerCore/OPmodel.jpg}{0.5\tw}{Tokamak/Transformer/ToroidalElectricField/SchemaTransformator.jpg}{Schematic view of tokamak GOLEM iron transformer core}{Fig:Transformer} }
