Abstract

In order to analyze the mechanism of magnetic shaking, the permeability and the energy losses for a small amplitude, low-frequency exciting field are studied under magnetic shaking in comparison with those under the normal condition (without shaking). The permeability and the energy losses were measured for a Metglas 2705M amorphous ribbon wound core by a lock-in technique in the frequency range of 1-20 Hz under both magnetic shaking (2.7 A/m, 1 kHz) and the normal condition. The effects of the magnetic shaking on the domain wall pinning, the mean wall velocity, and the number of the active walls are described. The strong frequency dependence of the enhanced incremental permeability even at low frequency is explained as a result of these effects.
