A simple question,
I read that the particles in a plasma (protons , electrons) travel along the B field lines in a plasma which I know and they loop around the field lines each in opposite direction (clockwise, anticlockwise ) but both in the same direction.
My question then is this. If I have a straight evacuated tube in which a gas mixture is inserted, on the outside of the tube I have a solenoid (wires wound around much like on a solenoid core) now I apply a DC current to the coil and (by some means) turn the gas into a plasma state. So through the plasma filled tube I have B field lines from my outer DC coil, the particles inside the tube follow those lines, does my DC coil current and the resulting plasma current are in the same direction then?
The green arrow shows the (supposed direction of ) the plasma current while the drown one shows the direction of my DC current.
I hope I explained my question clearly
