On the Quasi‐Three Dimensional Configuration of Magnetic Clouds
On the Quasi‐Three Dimensional Configuration of Magnetic Clouds
We develop an optimization approach to model the magnetic field configuration of magnetic clouds, based on a linear-force free formulation in three dimensions. Such a solution, dubbed the Freidberg solution, is kin to the axi-symmetric Lundquist solution, but with more general "helical symmetry". The merit of our approach is demonstrated …
