Abstract: Magnetic shielding effectiveness of various kinds of soft magnetic materials from electrical steel sheets to amorphous and nano-crystalline ribbons was examined in the shields of same size and same thickness in the electromagnetic field of extremely low frequency range. The evaluation of material's factors for shielding effectiveness is studied and the practical selection of shielding materials was tried technologically.
