Abstract
The device has an electromagnetic ultrasonic transducer (1a) and an airborne sound transducer (2a) that are provided on either side of a workpiece (3). A permanent magnet (10) is arranged in parallel to the electromagnetic ultrasonic transducer for creation of alternating electromagnetic field in the workpiece. The alternating electromagnetic field induced in the workpiece is detected using a high frequency coil (13). An independent claim is included for a method for contactless excitation and reception of ultrasounds in workpieces.
