Abstract
Axially symmetrical waves on the surface
of a ferromagnetic viscous-fluid film
flowing down a cylindrical conductor
with alternating current are considered.
In this case, in addition to the
gravitational force, the film is
affected by a spatially nonuniform time-
dependent magnetic field. The film
thickness was assumed to be small
compared to the radius of the conductor.
In the long-wave approximation, a model
equation for the deviation of the film
thickness from its undisturbed value is
obtained. Some numerical solutions of
this equations are reported.
