Voltage rectification effects in mesoscopic superconducting triangles: experiment and modelling [PDF]

, 2007
The interaction of externally applied currents with persistent currents induced by magnetic field in a mesoscopic triangle is investigated. As a consequence of the superposition of these currents, clear voltage rectification effects are observed.

Swarm Observations of Dawn/Dusk Asymmetries Between Pedersen Conductance in Upward and Downward Field‐Aligned Current Regions

Earth and Space Science, 2021
The locations of region 1 and 2 field‐aligned current systems were determined using fluxgate magnetometer measurements from 875 dawn‐dusk passes of the Swarm A satellite.

DYNAMICS OF THE FIELD-ALIGNED CURRENTS DISTRIBUTION ASYMMETRY DURING SUBSTORMS IN THE EQUINOX SEASON

Solar-Terrestrial Physics, 2021
We continue to study the physical processes occurring during the August 17, 2001 magnetospheric storm by analyzing the dynamics of the intensity of field-aligned currents (FACs) in Iijima—Potemra Region 1 in the polar ionospheres of two hemispheres ...

South-north asymmetry of field-aligned currents in the magnetotail observed by Cluster [PDF]

, 2010
We statistically investigated features of the field-aligned current (FAC) distribution in plasma sheet boundary layers between 17 and 19 RE in the magnetotail using the curlometer technique to calculate the current from four-point magnetic field ...

Magnetosphere-ionosphere coupling currents in Jupiter's middle magnetosphere: effect of magnetosphere-ionosphere decoupling by field-aligned auroral voltages [PDF]

, 2005
We consider the effect of field-aligned voltages on the magnetosphere-ionosphere coupling current system associated with the breakdown of rigid corotation of equatorial plasma in Jupiter's middle magnetosphere. Previous analyses have assumed perfect

Magnetotail reconnection: Current diversion and field‐aligned currents

Geophysical Research Letters, 1991
We have used a three‐dimensional resistive and compressible MHD code to study reconnection in a magnetotail configuration. The initial state is a two‐dimensional equilibrium with a northward magnetic field component Bz across the current sheet. Reconnection is initiated by applying a finite resistivity localized in the near‐Earth region with a finite ...

Field‐aligned current distribution in the transition current system [PDF]

Journal of Geophysical Research: Space Physics, 2004
The interactions of coronal mass ejections with the Earth's magnetosphere are interesting because they often lead to extreme forcing of magnetospheric convection. Here we consider the initial interaction of a CME with the magnetosphere for the specific case in which there is a sharp increase in the dynamic pressure (interplanetary shock) that is ...

SwarmFACE: A Python package for field-aligned currents exploration with Swarm

Frontiers in Astronomy and Space Sciences, 2023
The SwarmFACE package utilizes magnetic field measurements by the Swarm satellites to study systems of field-aligned currents (FACs). Improvements of well-established techniques as well as novel single- and multi-satellite methods or satellite ...

Current‐voltage relationship in downward field‐aligned current region [PDF]

Journal of Geophysical Research: Space Physics, 2005
Field‐aligned electrons accelerated upward from the ionosphere to the magnetosphere are the principal charge carriers in the auroral downward field‐aligned current region. Current densities, typically of the order of a few μAm−2, are sustained by potential drops of several 100 V up to a few kV.

Timescales of Birkeland Currents Driven by the IMF

Geophysical Research Letters, 2019
We obtain current densities from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE), alongside By and Bz from the Interplanetary Magnetic Field (IMF) for March 2010.
