| Abstract: | An analytical solution is found to the vortex electron anisotropic hydrodynamic equations that describe the nonlinear evolution of the long-wavelength Weibel instability. The presented analytical approach shows that the long-wavelength Weibel instability saturates without a decrease in the temperature anisotropy in the single-mode regime due to the rotation of the anisotropy axes. The generated magnetic field is circular-polarized, and its amplitude varies periodically in time. |
