Localised specific power loss was determined for surface treated Metglas ((R)) 2605SC amorphous ribbons. The energy saving was maximum if the inhomogenity was reduced by polishing both surfaces. However, a further saving was noticed on the scratched samples. The optimum scratching interval for maximum energy saving was found to be 3 mm. The anomaly factor was also found to alter due to the domain wall spacing and loss measurement. The experimental findings showed that existing theory can reliably explain the power loss in amorphous ribbon.
