Magnetic shielding of electromagnetic fields in the frequency range from 0 Hz to 50 kHz

摘要

A magnetic shield (1) has for shielding of electromagnetic fields in the frequency range from 0 Hz to 1000 Hz at least one layer (3, 4) of a non-grain-oriented ferromagnetic material. The at least one layer (3, 4) leads at a low cost to a good shielding effect.
