Abstract

According to the invention, the device includes at least two juxtaposed sheets, each of the said sheets having anisotropic magnetic properties and a high permeability, so that it exhibits a direction of lowest reluctance, the said sheets being positioned in the magnetic field in the vicinity of the sensitive system in such a way that each of the directions of lowest reluctance exhibits a different orientation so as to attenuate the magnetic field passing through the said sheets. Application to the manufacture of a screening case for cathode-ray- tube consoles. <IMAGE>
