Experimental results of the study on sound speed distribution in a non-uniformly magnetized magnetic fluid are considered. The sound speed in the magnetic liquid within the measurement error does not depend on the magnetic field gradient, which it is exposed to. This fact does not completely preclude the possibility of the sound speed dependence on the magnetic field gradient predicted by the well-known theory. However, the estimates and the known literature data do not support the statement on the exclusive role of this parameter. Tables 2, Figs 10, Refs 9.
