The engineers at Magnetic Shield Corporation are available for consultation regarding the specifications of magnetic shielding. The following is a basic method for determining an approximate shield design. Engineers at Magnetic Shield Corporation are available for consultation on calculations. In that case, choose two layers of equal thickness, totaling at least the required thickness. For multilayer shields, the H i from the outermost layer becomes H o for the next layer.
Attenuation is calculated in a similar manner for each layer.
Attenuation factors calculated in the above manner give theoretical attenuations only attainable in ideal conditions. Some theories maintain that attenuations of this magnitude are only possible with ideal combinations of spacing, annealing and shape.
