Ok so i have a question , for the sake of the argument imagine a infinitely long conducting wire with a given positive potential. Now along that wire in an enclosed non conducting tube around it there is a ionized hydrogen (no electrons for the argument) Now when a conductor like our infinitely long wire is at a potential there are electric field lines pointing outwards from the wire which are 90 degrees to the wire or perpendicular in all directions. Since there is positive potential int he wire our ionized hydrogen protons are repelled from the wire , we could say the electric field from the charges on the wire is pushing against the protons and vice versa , so they tend to bend away from the wire? Now imagine an small insulator along the length of the wire around it , the same situation wire at a potential , protons along it's sides , insulator between them , outer tube to enclose and confine the ionized hydrogen gas. Now what happens when I add current to the ionized hydrogen , at both ends using electrodes ? Now there is a current flow because of the conducting properties of the ions , now that creates a magnetic field , the question then is how does this magnetic field act in the situation , does it pushes the ions further from the wire contributing to the already existing electric field perpendicular to the wire or does it act against it ? Normally the magnetic field is perpendicular to the electric field but this situation is slightly different.i guess.
