Dec 16, 2021 at 12:36 comment added Physor Yes I thougth about that tiny short current because of induction, but I was talking about the man current that flows in the steady state. Thanks for the comment by the way
Dec 16, 2021 at 12:35 comment added AccidentalTaylorExpansion No I think that this discussion is useful to see because other people might think the same. I'm also no expert myself in EM so I could be wrong as well
Dec 16, 2021 at 12:32 comment added Physor should I remove my answer ?
Dec 16, 2021 at 12:31 comment added AccidentalTaylorExpansion Veritasium is wrong in the sense that this current will be too tiny to light up any physical light bulb but in theory a small current will go through the bulb.
Dec 16, 2021 at 12:31 comment added Physor What about the first point ?
Dec 16, 2021 at 12:30 comment added AccidentalTaylorExpansion Veritasium is only slightly wrong. In theory a switch closing anywhere in the universe is enough to "light up" the bulb. A closing switch causes an electromagnetic disturbance that travels outwards. That can cause a non-zero Poytning vector in some other nearby wire and in turn that can create a small current . See also this video… . Every realistic wire has some inductance so you can see this setup as a transformer with very large spacing between the two coils.
