A "non force-free" model for the magnetic field and plasma study of the Magnetic Cloud

In this work we present an improvement of a previous non force-free model for the study of the magnetic topology of the magnetic clouds (MCs) which now incorporates an analysed of the behaviour of the pressure of plasma inside the MCs. The model is fitted to the experimental data of the three components of the magnetic field in the GSE cartesian reference system and the plasma pressure measured by the spacecraft.
