Magneto-acoustic-electric detection method and device for defects of high-conductivity non-ferromagnetic material

The invention relates to a defect detection method and a defect detection device, in particular to a magnetoacoustic-electric detection method and a magnetoacoustic-electric detection device for defects of a high-conductivity non-ferromagnetic material. The invention discloses a magneto-acoustic-electric detection method and device for defects of a high-conductivity non-ferromagnetic material, which can effectively improve the spatial resolution of detection and overcome the defect that only surface defects can be detected due to a skin effect in eddy current detection through a multi-physical field coupling effect of a sound field and an electromagnetic field. A magnetoacoustic-electric detection device for defects of a high-conductivity non-ferromagnetic material comprises a data acquisition system which is used for acquiring detected defect voltage data of the high-conductivity non-ferromagnetic material. According to the method, the sound field and the electromagnetic field of the nondestructive testing o
