    摘要: A magnet core wound from a soft magnetic strip is required to have a relative permeability μr which is enhanced by reducing mechanical stresses. For this purpose, the soft magnetic strip is coated with a static friction reducing material on at least one side. This is at least partially burned off during the heat treatment of the magnet core. Its annealing residue is left behind, so that layers of soft magnetic material alternate with layers of the annealing residue of a static friction reducing material in the cross-section of the magnet core.
