| Abstract: | The feasibility of generating additional acoustic harmonics in the geomagnetic field during the propagation of an acoustic wave in a conducting medium through a region with a variable electromagnetic field is considered. Two possible mechanisms of such generation are analyzed: a parametric mechanism and a mechanism associated with ponderomotive forces (dynamic). Expressions are derived for three acoustic harmonics generated by a magnetic dipole with a variable magnetic moment. |
