Experimental studies were performed, which are aimed at development of electromagnetoacoustic transducers with smallsized pulsed sources of the magnetic field. Possibility of development of transducers with flat two-window magnetization coils is shown. They provide formation of the magnetic field with up to 1 T induction during the time of impact of magnetization pulse of up to 200 μs with 600 A current with short switching on and off time. Electromagnetoacoustic transducers with new magnetization coils ensure obtaining backwall echo pulses with more than 20 dB amplitude, compared to interference amplitude. 13 Ref., 2 Tabl., 10 Fig.
Keywords: electromagnetoacoustic transducer, magnetic field, high-frequency electromagnetic field, ultrasonic wave pulses, magnetization pulse, ferromagnetic product; inductance coil, control, diagnostics, thickness measurement
