Good day, from what I read we can make a vacuum in an enclosed space and we can inject or keep electrons in that vacuum , I hope that far I am right.Vacuum is a good , the book says the best insulator of electrical current, since it has basically no particles or medium for the current to run through,
so if I have a box with enclosed vacuum inside and two metal contacts at each side , when applying a voltage across them no current flows , now I wonder what would happen if i had the vacuum box but this time with a certain amount of electrons in that box , would it then act as a conductor depending on the amount of electrons in that space or no? I know a metal conducts because of free electrons in it's lattice atoms and air conducts when ionized when electrons are stripped off of neutral atoms but how do the electrons act in vacuum would they form a current path ?
also if a current path would form between the contacts in the sides of my box , could i disrupt the current by pushing the electron beam or path away from the contacts with a magnetic field or by electrosatic means , like adding a positive plate outside the box away from the contacts so dragging the electrons close to a side with no contacts on it ?
