Spiral Galaxy Magnetic Field

I thought Thunderbolts Project and Gareth at See the Pattern were using the same playbook for an electric universe, but I see a divergence.

I recently watched the attached video though it is from a year ago.

Alfven's galactic  circuit is different than TBP's Don Scott's circuit.

Hopefully I am summarizing this correctly.

Don describes the axial birkelund current pair creating a galactic magnetic field which drives the observed motion in the disk. At the core, the current splits into a filament to each arm eventually returning to the core at the galactic poles. The bend at the core is the source of high energy synchrotron radiation.

Gareth describes the Alfven circuit as somewhat  the opposite:

The current  pivots at the core travelling along the disk returning from the edge where it splits  to return to the poles.

The motion of the spiral arms is driving the magnetic field; Alfven even calculated the energies in the disk motion and in the field.

Both agree the galactic birkelund current is in the galactic disk, with its arms.

Gareth notes Alfven's circuit does not explain the disk rotation but explains other observations like the double radio lobes.

Don explains the rotation but this double lobe scenario is not mentioned.

A 2010 study in Spain concluded the observed rotation curve in M31 is from its measured galactic magnetic field.

A 2015 study in Germany concluded the observed structure in the IC342 spiral galaxy arms was from the detected magnetic fields.

From these studies:

There are multiple magnetic fields in a spiral galaxy.

My personal observation as one who is not an astrophysicist:

Gareth describes the galactic disk as a defined entity.


I find this enlightening. An elliptical galaxy like M87 has a plasmoid at the center so I assume there is an axial birkelund current supplying its energy. I find no reference to a magnetic field around M87.

M87 does not rotate and has no disk or arms.

Gareth's scenario has other results.  A spiral galaxy has a bulge which I believe has little or no rotation so the disk appears separate from the bulge where rotation begins.

The M31 disk rotation curve shows no motion at the core with a maximum velocity around 30Kly from center at around 270 km/s and flattens around 60 kly and beyond at 220 km/s (disk edge is at 110 kly).

M64 is an odd galaxy with counter rotating disks beyond the inner disk which is out to 2.3kly having no structure (like arms); its disk outer edge is at 27kly.

M64 definitely has a disk with unique behaviors.

Cartwheel galaxy has a ring with a large gap from the core area with spokes from core to ring visible in different frequency ranges. This outer ring rotates at 317 km/s. A magnetic field must be driving the rotation of this detached ring around the core.

from Wikipedia:

[M64] was discovered by Fritz Zwicky in 1941. Zwicky considered his discovery to be "one of the most complicated structures awaiting its explanation on the basis of stellar dynamics."

my comment:

I found no explanation so it is still waiting.

However, I recall Don Scott proposed the known behavior in a plasma filament having counter-rotating currents can apply to such galaxies.

There is agreement on magnetic fields in spiral galaxies but different explanations for the galaxy's.

The plasma universe site (by Peratt) shows simulations of a birkelund current pair resulting in various spiral galaxy shapes.

There are no results like an elliptical galaxy but the description states both elliptical and lenticular galaxy types are observed as well as spirals.

I assume Peratt being a student of Alfven uses Alfven's model for this simulation.

Cosmologists working with plasma physics do not yet agree on galaxy formation and behaviors. They agree gravity has little if any role which is the consistent message of an electric universe.

Based on only explaining elliptical galaxies, I suspect Alfven and Peratt might have the better explanation of a galaxy.

Electric Universe cosmology has a task for explaining galaxies which is still missing details for consistency.
