Physics/Is it possible to create non-thermal plasma by heating a gas and deflect the plasma ions from containment wall by magnetic field?

Question
Imagine a column of gas. By heating the gas to about 1000K, there will be certain degree of ionization of the gas, creating a mixture of ions and gas atoms. As the ions and atoms are in random motion, the ions will be deflected from the walls imbued with magnetic field if they are moving towards it, but atoms should not be affected. In this way, will the plasma formed be concentrated at the center and surrounded by the neutral gas? (Ignoring plasma radiation cooling and assuming that the temperature is constant.)

Answer
At only 1000K?  Good luck with measuring any real effect from that.  You never said anything about the structure of this magnetic field at all, or the density of the gas...but the ionization will be extraordinarily minimal at only 1000K.  So no, it should do nothing noticeable at all.

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
