I What causes ring current?

  1. May 11, 2017 #1
    Is ring current caused by gradient-curvature drift? I can't find a website that explicitly says that, they just call it 'longitudinal drift' and don't specify the mechanism, which I assume is particles drifting from one field line to the next - i.e. grad B drift and curvature drift?

    Oh sorry, I meant in the Earth's magnetosphere.
