Dynamic behaviour of magneto-acoustic emission in a grain-oriented steel

Original language description

Magneto-acoustic emission (MAE) in a grain-oriented electrical steel is measured in a wide range of the magnetizing frequencies fmag=0.5-100Hz at the controllable sinusoidal/triangular waveforms of the magnetic induction B(t). Magnetic field is measured directly by a Hall sensor positioned on the steel surface. Intensity of the MAE signal (rms value) follows a loss separation formula afmag+bfmag+c and reveals a linear relationship with the hysteresis loss. Number of the MAE individual pulses drops with the magnetizing frequency hyperbolically. Shape of the induction waveform at the fixed magnetizing amplitude and frequency has no visible impact on the above-mentioned behaviour. However, rms profiles of the MAE signal are driven by the field rate of change dH/dt. Integration of the MAE profiles allows to evaluate the hysteresis coercive field.
