I meant to say fast moving "objects" in the title, my bad... my title kind of sucks
https://en.wikipedia.org/wiki/Relativistic_electromagnetism#The_field_of_a_moving_point_charge
That section is basically what my questions are about. I want to know generally about the overall forces. Two protons in the LHC moving the same direction will not experience much repulsion difference relative to their own perspective, but from our perspective outside the LHC their repulsion should weaken? The repulsion of two protons without electrons I mean.
But two protons colliding in the LHC going opposite directions. Because their speeds are not relative, they would have increased repulsion? I can't understand the wikipedia article that well. I think it's saying the increased repulsion would be from the sides as they pass each other (assuming they didn't collide)?
ok, one more question about, voltage and current, that i guess kind of has to do with time dilation. If you took a beam of fast moving electrons, could that create a voltage for a wire or something near by right? I mean of course a wire with current would create a voltage, but would it also work for a beam of electrons in a vacuum? How come electrons are supposed to repulse other electrons, but a voltage creates a current? thanks
