SUMMARY

The discussion centers on the persistence of the ring current in planetary magnetic fields despite the short life expectancy of its particles, which ranges from hours to days. Participants highlight the contradiction between the compromised azimuthal drift of these particles and the existence of a significant current that influences geophysical effects. The conversation emphasizes the need for a deeper understanding of how transient particle dynamics can still contribute to stable current phenomena in planetary magnetospheres.

PREREQUISITES
  • Understanding of planetary magnetic fields
  • Knowledge of particle dynamics in astrophysics
  • Familiarity with azimuthal drift concepts
  • Basic grasp of geophysical effects related to magnetic currents
NEXT STEPS
  • Research the mechanisms of ring current formation in planetary magnetospheres
  • Study the effects of azimuthal drift on magnetic field stability
  • Explore the life cycles of charged particles in space environments
  • Investigate the geophysical implications of transient current phenomena
USEFUL FOR

Astronomers, astrophysicists, and geophysicists interested in planetary magnetism and the dynamics of charged particles in magnetic fields.

TL;DR
Ring current, azimuthal drift and typical particles life expectancy
I read that "the azimuthal drift is compromized because the typical life expectancy of ring current particles is only hours to days and thus of the same order of magnitude as the drift period". But, if it is so, why relevant current exist? How could we armonize the fact that the azimuthal drift is "compromized" and there a current that we have to consider, at least for its geophysical effect?

I read that
Please give us the reference to that. And you are asking about planetary magnetic field phenomena, right?
