Physical interpretation of magnetostatic shielding
Source abstract
Abstract
Plausible physical mechanisms of the effect of a magnetic shield are considered. The shield is treated as a shunt for magnetic flux, as a compensator of an external field by means of fictitious magnetic charges, and as a solenoid compensating for an external field by means of molecular Ampere currents. None of the listed mechanisms taken separately can account for all aspects of magnetic shielding. This effect can be described adequately only if a complex approach is endorsed. Examples of calculations and measurements of magnetic parameters of shields, and their designs are presented.
