    "abstract": "We propose an analytical model based on the solution of the\nmagnetohydrodynamics (MHD) equations for studying the origin of intrinsic\nmagnetospheres. For this purpose, we reveal a new gauge condition for the\nelectromagnetic vector potential, which eases the solution of such complex\nsystem of non-linear equations. Using this model, we analyse the deformation of\nthe terrestrial magnetic field due to the presence of the solar wind. By\ncomparing with experimental observations, we have found that the geometrical\nconfiguration of the magnetosphere, before, and after the magnetic field of the\nEarth started to deviate the solar wind, has not changed notably, and that the\nsolar wind should have had a finite conductivity. This model can also be used\nto perform linear stability analysis of fluid and magnetic instabilities.",
