Abstract: The propagation of nonlinear waves along the surface of a cylindrical jet of magnetic fluid in the presence of a strong axial magnetic field is studied. It is demonstrated that, in the case of a liquid with high magnetic permeability, axisymmetric perturbations of the jet boundary of arbitrary amplitude can propagate along it without distortion. The analogy with known solutions describing the propagation of Alfven waves in an unbounded perfectly conducting fluid is discussed.

Keywords: ferromagnetic fluid, axial magnetic field, jet, nonlinear waves, exact solutions.
