"Viscous" Interaction Besides the merging-reconnection interaction of the solar wind plasma with the magnetosphere, there is believed also to be a "viscous" interaction setting up a vortex motion in the magnetosphere even when no merging is occurring. This interaction is due to drag on the outside of the flux tubes threof the flux tubes threading the magnetopause, caused by the solar wind passage along the flanks of the magnetosphere: The image dipole analogy In passing we can mention that another way of looking at the field shape within the magnetosphere is to consider it like the classical representation of what happens when a magnetic field is brought up to an infinitely conducting sheet; this acts as if an "image dipole" were created:

Radiation Belts We looked previously at the motion of a charged particle in a magnetic field when we studied the IMF. The same v x B force will cause particles to spiral around the earth's magnetic field lines.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
