Turbulent Erosion of Magnetic Flux Tubes
Results from a numerical and analytical investigation of the solution of a nonlinear axisymmetric diffusion equation for the magnetic field are presented for the case when the nonlinear dependence of the diffusivity nu (B) on the magnetic field satisfies basic physical requirements. We find that for sufficiently strong nonlinearity (i.e., for
