Okay because my previous post of similar kind was I guess rather too full of thought experiments and ideas that nobody actually responded to it except for one user then I will try to explain the same thing here only much simpler. A few situations. so there is this site http://physics.weber.edu/schroeder/mrr/MRRtalk.html Now scrolling a little bit down you can see the picture with the charged plates and charges. Instead of accelerating the plates like told in the site what would happen if A) Two parallel plates , electrostatic field between them , the plates themselves insulated and a flow of charges like ions between them with electrodes at both ends to drive the current.The question is do those flowing charges flowing perpendicular to the E field experience length contraction , also do charges flowing perpendicular to an E field create a magnetic field which then acts as a "back" emf or counter electromotive force and pushes against the flow of charges in this situation which created it in the first place , so does this back EMF then works to make the length contraction even stronger? B) if say our point charge is a proton , now if it would experience length contraction that would mean that it's field infront of the particle in the direction of motion would get weaker right? does that mean that if two protons would be on a collision course being length contracted they would require less energy to smash together as the e field of them would be weaker in the parts of impact ?
