Abstract :
This paper presents the study of 2-layer shielding against power frequency magnetic field in order to increase the shielding effectiveness of the shield. The work has been investigated by finite element method (FEM) considering the hysteresis effect of magnetic materials. The investigations show that the shielding effectiveness of the shield is affected by several factors: the nonlinear property of materials, order of materials, spacing between layers, etc
