When two or more concentrically spaced magnetic shields are layered and magnetically isolated, the attenuation of the external field is multiplied. This multiplying effect of successive shields provides substantially greater attenuation of magnetic fields than a single shield of equivalent total wall thickness.
The mica group of sheet silicate are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition.
The characteristic of mica is explained by the hexagonal sheet-like arrangement of its atoms.
