Yes, an electromagnetic field can coax charged particles into forming a current, but its mere presence does not mean there is current. Electromagnetic fields happily exist in vacuum where no current is possible.
And yes, electric currents can be formed by free electrons, not just ionised gas (i.e. plasma).

can coax a what now?
A magnetic field
only exists with a
change in the e-field, this change is described as an
electric current. This is EM law.
an M field does not just 'exist'... The context of my post was about the
magnetic fields detected in the sun...
Where are we going with this steffen? We need a conductor.

Sunpsots are a surface phenomenon of the Sun's photosphere, they don't open up to any appreciable depth into the Sun's interior...certainly nowhere as far as the core!!

Yep... my point exactly.... So why is there a difference in the n-flux when the holes form?
