Abstract :
An improved method for measuring uncertainties in the magnetization process in the saturation region is described. Preliminary results indicate that uncertainties occur in Permalloy tapes for magnetic intensities as high as 30 times the coercive force. Above this intensity, the discontinuities rapidly disappear, indicating that fields of this magnitude are required for complete saturation. No uncertainties are observed in the saturation region during demagnetization.
