Calculation of electromagnetic laying-in transducer in the regime of recording of ultrasonic waves in metallic rods and pipes

Acoustic bulletin, Vol. 11 ¹ 4, (2008) p.44-53
The offered approach to analytical describing of characteristics of the electromagnetic transducers in the regime of recording of ultrasonic waves allows the developing of mathematical models of transducers containing the complete set of geometric and physico-mechanic parameters of real objects. The approach effectiveness is demonstrated on the example of the laying-in transducer which receiver of the alternate magnetic field consists of two pancake multiturn frames located over the lateral surface of the ferromagnetic rod with circular cross-section.
