In 1953, Syrovatskij found that the magnetic field has the stabilizing effect on Kelvin-Helmholtz instability. He studied the linear stability of the current-vortex sheet and introduced the Syrovatskij linear stability condition. In this talk, I will present nonlinear stability of current-vortex sheet in the ideal incompressible Magneto-Hydrodynamics under the Syrovatskij stability condition. I will also talk about the stabilizing effect of magnetic field on the plasma-vacuum problem.
