MAGNETOELASTIC ELECTROMAGNETIC ACOUSTIC TRANSFORMATION. Part 3
(pp. 20-29)

Abstract. The calculation of projections induction secondary field in the air, appearing after a double electromagnetic acoustic transformation in solid ferromagnetic, a conducting body due to magnetotlastic of transformation mechanism fields. Unlike the electromagnetic mechanism of interconversion acoustic and electromagnetic the fields at the magnetoelastic mechanism of transformation an informative parameter is E.M.F., induced by the normal component of induction of the secondary field in a measuring сoil. Found that the relationship between the amplitude of induction of the secondary field and the EMF induced in the reception of the inductive coil, largely changed when you change the size of the inductor. Comparison of the experimental data to measure the topography of the secondary field with the results of the calculations are shown good their consistency.

Keywords: double electromagnetic acoustic transformation, magnetotlastic mechanism, components of the secondary electromagnetic field.
