A system for non-destructive inspection that generates Shear Horizontal waves in phased array configuration using an Electro Magnetic Acoustic Transducer (EMAT). The system includes an EMAT transducer with a plurality of elements made of individually wound elements under a single magnetic field, and an instrument to pulse, receive and record the signals from each element separately. Each wired element in the array generates shear waves perpendicularly to the coil windings which radiate around the elements' long axis. By phasing the pulsing and receiving of the individual elements, the beam can be electronically focused at different angles in the component from 0° to +/−90°. The compact distribution of the array permit using relatively high frequencies without generating deleterious grating lobes.
