Assembly and method for inductively charging mobile devices

The primary side (P) of an arrangement for inductively charging an electrically operated device (F) has a primary coil with at least two windings (1, 2, 2a, 2b). Each second winding (2, 2a, 2b) has a lower number of turns than the first winding (1) and is arranged radially outside the first winding (1). The winding direction of the second windings (2, 2a, 2b) of the primary coil (P) is opposite to the winding direction of the first winding (1).
