摘要：

The experimental research of the magnetostatic shielding effectiveness and the analytical calculations of the average magnetic permeability of single layer cylindrical sample of the shields based on electrolytically deposited Ni80Fe20 alloy are carried out. The locations of maxima on the Ef(H) and mu(H) curves do not match each other, which is difficult to interpret in terms of the shunting model. The results are explained by the non-linear distribution of the magnetic permeability through the thickness of the shield, It has been shown that in the magnetic fields range from 100 A/m up to 2700 A/m, the shields based on the Ni80Fe20 alloy are preferred over ones based on the 84KHSR amorphous ribbon. It is concluded that at the selection of shield materials it should Lake into account not only the main magnetic characteristics - mu; IIs; IIc but also IImax parameter, which is important to evaluate the effectiveness of magnetic shielding.
