Abstract (en)

[origin: EP0542200A1] Magnetic material for coil cores of inductive components which are used in the presence of high external magnetic fields, in the case of which magnetic material the internal magnetic field strength is reduced by shear in that a homogeneous ferrite/plastic composition is provided having a mixing ratio which is defined by parameters of the maximum external field strength to be expected and the minimum permissible permeability. <IMAGE>
