ABSTRACT:
Hook- and loop-type tapes are selectively attached to a video display unit and to flexible elongated strips of magnetic material so that the strips of magnetic material may be removably mounted around the video display unit in orthogonally intersecting planes to absorb magnetic radiation from the source. Each strip of magnetic material has a grain orientation parallel to its longitudinal axis and may be formed from grain-oriented ferromagnetic material in the range from M3 to M7. A multiple-layer magnetic shielding material is provided by securing first and second layers of such grain-oriented ferromagnetic material together with the grain orientation of the first layer orthogonal to the grain orientation of the second layer. Each strip of magnetic material may also be formed from this multiple-layer magnetic shielding material.
