## Other plasma parameters

I would suggest adding Lundquist number and Magnetic Reynolds number --Samoojas (talk) 19:49, 1 July 2011 (UTC)

Would we also be able to add the strong coupling constant (not yet an article for it that I can find, but it is defined as the ratio of energy due to the electric field to thermal energy. NJHartley (talk) 13:44, 19 July 2012 (UTC)

## Electron gyrofrequency

I think the "c" in the gyrofrequency shouldn't be there. But I don't know much about plasma physics. Someone please, confirm. — Preceding unsigned comment added by 129.123.154.253 (talk) 01:36, 24 March 2014 (UTC)

## The formula for ion gyroradius appears to have a constant error.

The formula for this is off by 10,000, which looks like a flipped sign on the exponent of the constant up front (should be 1.02*10^-2), and/or it was checked in B units of Gauss rather than Tesla as I believe it should, under (coincidentally) Gaussian CGS units. I have not checked the rest of the page for the same error.

   r_i = v_{Ti}/\omega_{ci} = 1.02\times10^2\,\mu^{1/2}Z^{-1}T_i^{1/2}B^{-1}\,\mbox{cm}  — Preceding unsigned comment added by Pjwitham (talk • contribs) 17:17, 27 August 2014 (UTC)


## Conditions for Plasma

I would suggest adding a section with the conditions necessary for a plasma to be achieved. For example:

– Debye Length must me smaller than any typical length of the system, otherwise significant charge separations could arise and the plasma becomes dominated by some boundary effects

– Debye length must be statistically valid => there should be enough particles in a Debye Sphere: ${\displaystyle N=n(4/3)\pi \lambda _{D}^{3}\gg 1}$ (where n is the average density of particles)

And some other relations. Heitorpb (talk) 17:06, 17 October 2015 (UTC)
