Dynamical evolution of magnetic flux ropes in the solar wind
The conservation of magnetic flux in systems of very low dissipation, as the interplanetary medium, is used to analyze magnetic clouds in significant expansion. In particular, we analyze the fast and huge event observed at one astronomical unit in the solar wind on Nov. 9-10, 2004. We compare magnet...
