| Oct 30, 2013 at 13:59 | comment | added | Reds | I not sure if I completly understand your question but when there is a stationary charge next to the wire, you say that it is the magnetic force created by the current in the wire that repells the positive charge next to the wire. And when there is a charge that is moving along the wire with the same velocity and direction as the electron flow, then you say that because of SR the charge is repelled due to length contraction. I don't think I have much more knowledge of SR than you do, but I hope this helps. | |

| Oct 30, 2013 at 12:54 | comment | added | Mike Dunlavey | I'm not sure I can follow your question, but I hope you understand that for normal electromagnets the velocity of free electrons in the wire is quite slow, so I would not expect SR to have noticeable effect. Also there is no change in charge density, any more than pumping water in a pipe changes the amount of water in the pipe. | |
