Abstract：The effect of wire saw technic on the soft magnetic properties of Fe87Si9B13 amorphous alloy at line frequency has been studied in the paper.It showed that the phase of the amorphous core at the joint-cutting was partly transformed from amorphous to crystalline by the wire saw method.It was also found that the soft magnetic properties decreased in a certain degree,e.g.the rest magnetic induction Br dropped dramatically,while the coercivity Hc and the loss value increased after wire saw on the magnetic core.However,different wire core technics had different effects on the soft magnetic properties of the cores,which decreased compared with that before cutting.Furthermore,the experiment results suggest that the magnetic properties of the wire-sawed core with "big V pattern" decreased in minimum.Hence,this pattern of wire saw is feasible in practice.
