Basharova, A. F., Nagovitsyn, A. A., Murav'eva, O. V.

Abstract. The paper deals with the possibility of increasing the magnetization field of the EMA transducer of longitudinal waves due to additional exposure to the current mag-netic field of the high-frequency inductor. A new methodology of calculating is proposed to assess the possibilities of increasing the efficiency of EMA-transducers of longitudinal waves for steels with known magnetization curves.

Keywords: ultrasound, efficiency of an electromagnetic-acoustic transducer, longitudinal wave, magnetization curve
