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.
