Abstract
Experimental data are given to show that the impression of an alternating magnetic field of constant amplitude on a ferromagnetic shield, called shaking, enhances the shielding factor against alternating external magnetic fields. Contrary to expectation the shielding is enhanced against disturbing frequencies both below and above the shaking frequency. It is shown that this effect cannot be explained by a simple model using the harmonics of the shaking induction.Keywords
