For my introductory course to electromagnetism (I'm an undergraduate student, so ELI5), I'm trying to get the right conceptual model of electron movement in a thin wire (with constant but non-zero cross section, like a cylinder) due to a constant current. It seems to me, that there are several contributing factors, and I wonder which dominate, and if some kind of order exists.
Electrostatic repulsion between electrons. If this was the only force at play, electrons should all travel on the surface of the wire.
Magnetostatic attraction caused by the magnetic field from charges in motion. If this was the only force then the electrons would all travel in the center of the cylinder.
Collisions with matter and thermal scattering, which would make the motion chaotic.
Material properties of the cylinder, and if in particular the cylinder is a metal, then I suspect that the lattice planes of the metal and orientation of these planes is somehow relevant.
Basically 1 and 2 create order, 3 and 4 seem to destroy it. I can't seem to find anything relevant in my courseware or online. Specifically I'm interested in common DC household wires.
