Abstract
The results represent the experimental investigations of the acoustomagnetic effect near the base of a cylindrical shell filled with a magnetic liquid. The theoretical interpretation of the effect of significant increase of the electromotive force (EMF) amplitude induced in the circuit in the vicinity of the base is given. The contribution to the measured EMF value of the demagnetizing field oscillation and of electromagnetic emanation caused by plane-parallel harmonic oscillations of a round metal membrane arranged in a direct annular magnet axially-symmetric field is discussed.
