ABSTRACT:
The present invention concerns a shielding material for a magnetic shield containing coal slag; silver powder; a mixture of calcium powder, magnesium powder, and zinc powder; and silica powder. The shielding material is in powder form. In another embodiment, the present invention contemplates adding nano-silver to the shielding material. The present invention is based on the concept that the magnetic field is actually “deflected” away from the area shielded. This is possible in view of the shielding materials used to produce the magnetic shield.
