Not exact matches
The simple fact that the maximum value of volume current density was increased with increasing
magnetic field line chaos, called «chaoticity,» suggests a direct proportionality
between the intensity of the current sheet and chaoticity.
In 2015, NASA launched the Magnetospheric Multiscale spacecraft to study the mysterious interactions
between Earth and the solar wind when our planet's
magnetic field lines occasionally break and reconnect, which also affects auroral activity.
The distance
between certain
lines in the spectrum reveals the strength of the
magnetic field in that location — information that can't be measured directly otherwise.
The UVIS images, which are also being analyzed by team associate Aikaterini Radioti at the University of Liege, Belgium, also suggest that one way the bright auroral storms may be produced is by the formation of new connections
between magnetic field lines.
Travis Horton at the University of Canterbury, New Zealand, plotted the migratory tracks from each species over a detailed
magnetic map of Earth, which shows how the
magnetic field's inclination and declination — the angular difference
between the
field lines and true north — vary from point to point.
Between pairs of opposite polarity,
magnetic field connections exist, represented here by
lines based on computer calculations.
