Abstract :
In this paper, in order to seek better material or better combination of materials for magnetic shells to which the magnetic shaking is applied, low-frequency magnetic noise is characterized under similar condition where magnetic materials are subjected to the magnetic shaking. Energy of the Barkhausen noise is compared to the fluctuation noise which appears in the low-frequency band when the magnetic material is excited with higher is excited with higher frequency such as 1 KHz.
