Like wow man! This thing is chock full of useful and useless stuff alike!

It defines such abstract terms as "frozen in" magnetic fields, fluxropes, fluxtubes, etc. etc. etc. Strangely, they leave out double layers...

Dig through it all, and see what's of interest...

fluxrope
A cylindrical body of magnetized plasma with twisted fields. Fluxrope topologies observed in interplanetary space have come to be known as magnetic clouds and are thought to be the interplanetary counterparts to coronal mass ejections.

fluxtube
The volume enclosed by a set of magnetic field lines which intersect a simple closed curve. A way of visualizing magnetic fields, a tube whose surface is formed by field lines. The strength of a fluxtube, F, is often defined as the amount of flux crossing an areal section, S, [equation] where dS is taken in the same sense as B to yield F ≥ 0. Fluxtube properties include: (i) the strength of a fluxtube remains constant along its length, (ii) the mean field strength of a fluxtube varies inversely with its cross-sectional area, (iii) a compression of a fluxtube increases the field and gas density in the same proportion, (iv) an extension of a fluxtube without compression increases the field strength. Examples of fluxtubes in the solar atmosphere are sunspots, erupting prominences and coronal loops, the Io/Jupiter system where Io injects ions into the Jupiter magnetosphere. Because of the localized source, these ions fill up tubes following the Jovian field lines to the poles, where they induce bright isolated auroral displays.
