A method for the supply of an electrical component with electric power using an inductive charging system having a primary coil unit and a secondary coil unit, where the electrical component is connected on a secondary side corresponding to the secondary coil, includes setting a rough position of the secondary coil unit relative to the primary coil unit to establish an electromagnetic coupling, displacing a primary coil in the primary coil unit relative to a primary ferrite in the primary coil unit in a preferred direction such that an electromagnetic coupling factor of the rough position of the secondary coil unit relative to the primary coil unit is increased, where the preferred direction lies in a plane of a planar basic shape of the primary ferrite, and changing a magnetically active surface area within the primary coil unit in the plane.
