Abstract:Here is examined the acoustic – electromagnetic transformation accompanying the propagation of sound wave through a magnetic nanofluid.The magnetic nanofluid was placed in the cylindrical resonator. An external magnetic field was applied along an axis of the cylindrical resonator. The induction coil was used to register local oscillations of the magnetic field. The signal was observed when the resonator was excited by the longitudinal sound wave with the frequency corresponding to one of the radial modes of the resonator. The parallel theoretical study supplies an interpretation of some of the experimental observations. An excitation of an electromagnetic field is shown to take place due to the perturbation in the magnetic permeability by a sound wave.
