Plasmas, Currents and Magnetic Fields
The source of all magnetic fields is an electric current.[1]
Ref 1 ... The source of all magnetic fields in a plasma are current systems
Your statement suffers from two serious weaknesses. First. "current systems" does not mean what you think it means. Second, it is far too simplistic, ignoring the two-way interaction between magnetic fields and charged particles.
What do you think a "current system" is? Or perhaps more appropriately, what do you think an "electric current" is? Most people, when confronted by the words "electric current" will think of a coherent flow of particles, all of which share the same sign of electric charge, as exemplified by the electric current flowing in the wires all around us. But that is not what "current systems" means in the paper you cited. To a plasma physicist a current system is simply any coherent motion of charged particles, even if the moving system of particles is at all times charge neutral, by which I mean that for any given unit volume, the total number of positively charged particles equals the total number of negatively charged particles, such that the net electric charge of the representative volume is zero. Hence, a plasma "current system" might easily not result in any
net motion of charge. Those charge neutral currents generate magnetic fields, a fact well know to both theory and experiment. So the idea that you must have a good old fashioned household style electric current to get a magnetic field is simply not true.
They call it
electromagnetism for a reason. It's
electro and
magnetism, they come together as a package, each feeding off of the other. Mechanical energy (like the energy of turbulent motion) in a plasma can be converted to magnetic energy, amplifying a small magnetic field into a large magnetic field. You overlook this amplification mechanism and naively assume that any magnetic field you see must have been directly generated by a non-neutral electric current flowing in place with the magnetic field. But that is well known not too be true. Not only can a plasma amplify a pre-existing magnetic field, but as we saw above, it can generate the field in the first place through dynamo action. So in no instance is any non-neutral electric current ever required in a plasma to get a strong magnetic field.
There is a huge physics literature on this and I find it somewhat amusing that the self-appointed champions of the alternate view are so incredibly ignorant of it. See, for instance,
Stellar Magnetism by Leon Mestel, Oxford University Press 1999, 2003. The whole book is obviously on point, but pay special attention to chapter 2 (
Theoretical Basis) and chapter 6 (
Stellar Dynamos); chapter 4 (
Magnetism and Convection) is useful for understanding photospheric magnetic fields in particular. There are plenty of other sources, but that should do for now. If you don't care enough to consult the references I offer, that's your affair. But if you keep repeating things known by physics to be false, while simultaneously ignoring that known physics, then your credibility on the matter is likely to be questionable at the very least.
