ABSTRACT:
The disclosed invention mounts transmitting and receiving electrical coils within channels or chambers formed by the notched ends of magnets closest to the metallic object under test where the magnets are arranged to form substantially annular arrays of an electromagnetic acoustic transducer pair applicable in non-destructive testing. The detection, preferably by tuned coils, of one or more electromagnetically-induced resonant frequencies at shifted locations indicates the presence of one or more flaws in the metallic structure under test.
