Abstract
An analytical solution is found to the vortex electron anisotropic
hydrodynamic equations which 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 one mode regime due to the rotation of the
anisotropy axes. The generated magnetic field is circular polarized and its
amplitude varies periodically in time.
