Current Systems in the Earth's Magnetosphere [PDF]
Reviews of Geophysics, 2018 AbstractThe basic structure and dynamics of the primary electric current systems in the Earth's magnetosphere are presented and discussed. In geophysics, the word current is used to describe the flow of mass from one location to another, and its analog of electric current is a flow of charge from one place to another.

Relation between the ring current and the tail current during magnetic storms [PDF]
Annales Geophysicae, 2005 We study the dynamics of the magnetospheric large-scale current systems during storms by using three different magnetospheric magnetic field models: the paraboloid, event-oriented, and Tsyganenko T01 models.

Two distinct current systems in the ionosphere of Mars [PDF]
Nature CommunicationsWhen the solar wind interacts with the ionosphere of an unmagnetized planet, it induces currents that form an induced magnetosphere. These currents and their associated magnetic fields play a pivotal role in controlling the movement of charged particles,

Dynamics of the Magnetotail Plasma Sheet Current
Atmosphere, 2023 Magnetospheric plasma can be investigated as a continuum by adopting magnetic field B and plasma flow u as primary parameters in the Bu paradigm or as a collection of individual particles by adopting electric field E and electrical current j as primary ...

Modeling of Magnetospheres of Terrestrial Exoplanets in the Habitable Zone around G-Type Stars
Universe, 2022 Using a paraboloid model of an Earth-like exoplanetary magnetospheric magnetic field, developed from a model of the Earth, we investigate the magnetospheric structure of planets located in the habitable zone around G-type stars.

Long-term evolution of magnetospheric current systems during storms [PDF]
Annales Geophysicae, 2004 We present a method to model the storm-time magnetospheric magnetic field using representations of the magnetic field arising from the various magnetospheric current systems.

Principal components' features of mid-latitude geomagnetic daily variation [PDF]
Annales Geophysicae, 2010 The ionospheric and magnetospheric current systems are responsible of the daily magnetic field changes. Recently, the Natural Orthogonal Components (NOC) technique has been applied to model the physical system responsible of the daily variation of the

The Mie representation for Mercury’s magnetospheric currents
Earth, Planets and Space, 2021 Poloidal–toroidal magnetic field decomposition is a useful application of the Mie representation and the decomposition method enables us to determine the current density observationally and unambiguously in the local region of magnetic field measurement.

Current systems in the Jovian magnetosphere [PDF]
Journal of Geophysical Research: Space Physics, 2008 The plasma dynamics in the Jovian magnetosphere is characterized by rapid rotation of the planet. In this paper, a new magnetohydrodynamic (MHD) simulation scheme is developed to precisely calculate the current systems in the Jovian magnetosphere and to relate them with the plasma dynamics. A field‐aligned current (FAC) pattern that is expected for the

Magnetospheric contributions to geomagnetic daily variations [PDF]
Annales Geophysicae, 1996 The contribution of magnetospheric current systems to geomagnetic daily variations is analyzed by means of a spherical harmonic analysis (SHA) using elementary models as well as the Tsyganenko model of the magnetosphere.
