Abstract
A core of a soft-magnetic material with a comparatively low saturation magnetization has layers of a soft-magnetic material with a higher saturation magnetization on the gap-bounding faces. To compensate for the uneven frequency response cause by the non-magnetic transition zones between the material of the core and the layers of soft-magnetic material, the layers of soft-magnetic material on the gap-bounding faces have different thicknesses.
