The doubt really came to me while trying to give a relativistic justification for magnetic phenomena, and I got stuck right at that point. I am afraid, however, that since we are dealing with the usual realm of the infinitely small, not only relativity but perhaps quantum mechanics is involved. The same analogy with the coil confuses me: in the coil you have a magnetic field (I think) precisely because you have a contraction of the distance between the electric charges inside the wire, but when you have, for example, a single elementary charge (an electron) what is contracting?

Any possible and available Insight is appreciated. Thank you very much.
