Abstract
An electromagnetic transducer is provided for ultrasonically inspecting conductive material as the material moves relative to the transducer. A coil is positioned in the field created by a magnet so that the conductors of the coil are transverse to the magnetic field. The coil is located predominately near the leading side of the magnet where flux is concentrated as the magnet and material move toward each other.
