Quick Plasma Question

  1. Oct 10, 2009 #1
    Recently I have heard that to contain a plasma, you need both an electric and magnetic field.

    I'd like to look into this more, does anyone know where I can find information on it?

    I cant remember where it is but look up a toroid plasma reactor thingy. It uses magnetic fields. Found out about it as we were making our amateur particle accelerator. The reactor starts with a T...thats all i know :)

    EDIT: Tokamak <---that's it.

    That's the problem.

    I can find articles on the EXISTENCE of a Tokamak, but nothing on the physics that I can understand.

    Maby that's the problem, I COULD just look up a bunch of papers on plasma confinement, but I know I wouldn't understand them..

    thanks very much

    wow...261 pages. I hope I have the time, perservearence, and knowledge to understand it all.

    It depends on the plasma.

    A candle flame, a very weak plasma, requires nothing to "contain it". A bolt of lightning is self-contained by its own electromagnetic pinch. The plasma in a neon sign is contained by glass (though it forms a sheath parallel to the glass surface). And the plasma in the Sun is almost contained by gravity (but it leaks out through the solar wind)
