    Current Drift Ring
AI Thread Summary
The discussion centers on the persistence of the ring current despite the short life expectancy of its particles, which typically lasts only hours to days. Participants question how a relevant current can exist when the azimuthal drift is compromised due to this limited lifespan. The conversation highlights the need to reconcile the existence of the ring current with the dynamics of particle drift. There is also a request for references to support the claims made about these phenomena. The topic emphasizes the complexities of planetary magnetic field interactions and their geophysical implications.

TL;DR Summary
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?

Please give us the reference to that. And you are asking about planetary magnetic field phenomena, right?
 
Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
