Abstract
A method for acoustic wave generation by electromagnetic-acoustic transducer in current-conducting medium of item under test consists in that emitter as a system of conductors is arranged above the surface of item under test, the item under test is subjected to effect of magnetic field formed by means of magnet with magnetic conductor with passing current pulse through the system of conductors. Simultaneously with passing current pulse through the system of conductors the magnetic conductor or item under test is subjected to stretching, compression or rotation, or magnetic conductor and item under test are subjected to stretching, compression or rotation simultaneously.
