Barkhausen Noise (BHN) Method can estimate stress of steel as a nondestructive testing. In this study, BHN probe with the 3 pole magnetization was manufactured. By using the BHN probe with the 3 pole magnetization, a rotating magnetic field was successfully formed. Moreover, the BHN measurement with grain-oriented electrical steel sheet was carried out. BHN measured with a rotating magnetic field accurately indicated the magnetic property of grain-oriented electrical steel sheet.
