Donald Scott presented an awesome talk at the Electric Universe 2014 conference (EU2014) on the shape of magnetic fields around plasma currents, with examples from planetary, galactic and inter-galactic phenomenon.
Here's the talk:

Dr. Donald Scott described his investigation of the inherent properties of Birkeland currents and subsequent discovery that they produce unexpectedly far-reaching magnetic fields in cosmic space. These fields collect matter and compress it into concentric hollow cylinders. They also produce a long-range attractive force on other such currents. Without involving mathematics, Scott describes the results of his analysis of the magnetic structures that are produced by, and that surround, Birkeland Currents. This work and its results gives new insight into the understanding of the electrical properties of space.
Dr. Scott earned his Bachelors and Masters degrees in Electrical Engineering at the University of Connecticut. He earned a Doctorate in Electrical Engineering at the Worcester Polytechnic Institute, Worcester, Massachusetts, and was a member of the faculty of the Department of Electrical & Computer Engineering at the University of Massachusetts/Amherst from 1959 until his retirement in 1998. During that time he was the recipient of several good-teaching awards and authored numerous scientific papers and chapters. In 1987, the McGraw-Hill Book Company published his 730-page textbook, An Introduction To Circuit Analysis -- A Systems Approach. In addition, Dr. Scott published the classic, Electric Sky (2006), 256 pages of compelling material on the Electric Universe and plasma cosmology.
Dr. Scott's paper: Magnetic Fields of Birkeland Currents (pdf) (http://electric-cosmos.org/BirkelandFields.pdf)
Here's the abstract from the above paper:
The fundamental vector calculus definition of a force-free, field-aligned, Birkeland current is expanded in cylindrical coordinates to obtain the partial differential equations (DEs) that yield the magnetic field created by such a current. The resulting equations are put into state- variable form and an Euler, step-wise, approximation incorporating a 4-th order Runge-Kutta algorithm is applied. In single-variable form, the DEs are identified as Bessel equations. J-sub0(r) and J-sub1(r) Bessel function solutions confirm the Euler results thus yielding closed form solutions for both the linking (azimuthal) and collinear (axial) components of the force-free field. Results show that both of these magnetic components reverse their directions and vary in magnitude in a way that aids the formation of concentric cylindrical shells of matter as has been observed in Marklund convection. Another result is the finding that magnetic fields extend relatively farther from Birkeland currents than they would from a straight-line current. They slowly decay as 1 over square root of r for large r.
Here's a glimpse at the sort of structures and fields formed in this manner:
