ABSTRACT:
An electromagnetic acoustic wave transducer (EMAT) probe is supported with its magnetic field issuing device for movement from a retracted position into closely spaced relation to a test object. Relative movement is provided as between a magnetic flux coupler and the EMAT field issuing device to derive the EMAT magnetic field from a magnet. A biasing unit urges the probe into its retracted position and the probe is moved into its operative position by magnetic interaction with a test object.
