Analog of the induction law for the magnetic Barkhausen noise
Original language description
The influence of coil turn number n and sample cross-section S on the Barkhausen noise signal has been studied. Combining the obtained results with our recent findings on the dynamic properties of the magnetic Barkhausen noise, we propose a Faraday-like relation for its rms envelope in the formU(rms) (H) proportional to root S center dot dH/dt. Validity of this relation is proved for classical sample-wrapping coils of the same geometry testing semi-hard thin ribbons of martensitic iron-based steel. The introduced square root dependence is explained by stochastic multiple overlapping of the independent Barkhausen pulses.
