Hi! My exams are coming up soon and I'm revising some of the notions of electromagnetism. What intrigues me is the way electric field is created/distributed within a wire. I've been thinking about it for some time and have come up with the following "hypothesis", idea:
When a conducting wire is connected to a positively charged body, the nearest free electrons of the wire will "jump" on the body (due to the force of the charged body acting on them) and thus "uncover" the positive charge of several nuclei in that part of the wire. These positively charged nuclei will attract electrons situated further along the wire, making them to move and "uncover" another set of nuclei. This process goes on and on until the end of the wire is reached. If this end is connected to a negatively charged body, the process is even more intensified.
What is your approach to this problem? Any help would highly appreciated, since it bothers me quite a lot :)
