And this causes an electromagnetic attraction effect around the wire?" Yes that is correct, however the attraction of same current direction parallel wire to the first is only due the magnetic macroscopic field. The electric field component E is shielded inside a current carrying wire and not radiated outside. Therefore the two wires interact only magnetically and not electrostatically. For previous comment, QFT does not use the bare model of the electron. Thanks for your link. | |

" IMO. I don't believe they have this in mind, mainly for illustration purposes unless it is explicitly stated in the illustration. There is famous recorded speech of Dirac emphasizing the problems with the bare model of the electron mainly adopted in the literature that prevents the deeper understanding youtube.com/watch?v=GlBWe6QM23k&t=293s (listen video from that time stamp and on). | |
| Nov 15, 2021 at 15:03 | comment | added | Tristan | "Therefore the bare electron model is characterized by the known literature as an elementary dimensionless-point massive particle which has created in the past much confusion an non-intuitive understanding. The actual physical form of the electron particle is dressed meaning it has a charge radius." So when the electron is described as a sphere (e.g. futurism.com/electron-edm-experiment), it is the dressed electron being described, not the bare one which is a point particle? | |
| Nov 15, 2021 at 15:02 | comment | added | Tristan | Thank you. Perhaps your wording is not considered mainstream, but I think I found your answer helpful. So your from figure, "E" is longitudinal the same as the current "I", and the "B" field is transverse? And this causes an electromagnetic attraction effect around the wire? Please correct me if my understanding is wrong. | |

| Nov 15, 2021 at 9:32 | comment | added | ACuriousMind♦ | I don't really know what this answer is saying but it's neither helpful nor mainstream physics. The notion of bare vs. dressed doesn't have anything to do with orthogonality of electric and magnetic fields. The answer is apparently using the term "manifold" to mean something other than its actual technical meaning, but never explaining what. "Electromagnetic quantum flux" is also not a standard technical term. | |
