1. A method for the production of ultrasound waves for nondestructive materials testing of a workpiece, which comprises:

  • providing at least one radio frequency coil disposed in an essentially uniform magnetic field, the at least one radio frequency coil having a coil axis disposed parallel to a surface of a workpiece; and

    producing horizontally polarized transverse ultrasound waves in the workpiece due to an interaction of the magnetic field with eddy currents in the workpiece, the eddy currents supplied by the at least one radio frequency coil.
