For your information, in Appendix A of this paper you can find out how to calculate the resistivity of a magnetized plasma (in the actual calculated situation, that of an accretion disk) in s/cm.
Nice paper M.Volwerk et al
However...
There are quite a few assumption i see.
The TOTAL RESISTIVITY of a conducting body (PLASMA) is inversely proportional to its dimension.
(paraphrasing as cant cant select text from the paper. Too lazy to type out verbatim)
This is a biggie! This is NOT what we observe in a LARGE (Dimensional) plasma, like the COSMIC WEB. Astrophysical Jets are implicated in this structure.
Lets NEGLECT the LONGITUDINAL CONDUCTIVITY, why?
It leads to equation (71) being mathamajikics!
'cos Mr Obvious asks "What would happen if the FORCE FREE conditions DID indeed BREAK DOWN?"
How would someone like tusenfem respond to that question?
While we are it, are you able to clarify what a "Force free magnetic link" is? Is the PLASMA flowing in these "LINKS"?
