Abstract: A novel design of eddy current probe based on rotating magnetic fields is presented for the inspection of steam generator tubes in nuclear power plants. A major advantage of the rotating field probe is that it offers the same functionality as that of a rotating probe coil without the need for mechanical rotation, which in turn translates into higher operating speed. The probe design is also sensitive to cracks of all orientations in the tube wall.
