Abstract: A device is described, which, according to one exemplary embodiment, includes a carrier which has a through opening along a longitudinal axis, and at least one soft magnetic strip wound around the carrier to form a toroidal strip core. The strip is wound directly onto the carrier so that there is no play between the toroidal strip core and the carrier. The carrier can thus serve as part of the housing of the toroidal strip core.
