just a copy of https://physics.stackexchange.com/q/422286/203741, maybe I'll get answers there
I'm on the way to understand em waves, but I decided, that I need to completely understand a current flowing. Not basics, not in general, I need to understand every trifle. I think, for a lot of people it will be very useful. Post only applies to induced current.
I will write, below, how do I understand things, if it wrong - correct me, and answer question during posting.
How does current induces
According to Faraday law, changing electric field generates changing magnetic field. How, and why does it occurs. Below, you can see fields of charge with $v=0, v=const;a=0,a!=0$.
The first case called electrostatics and describes by Coulomb law. If you confused, how does standing charge, that don't lose its energy, generates force, according to classic physics - well, I'm as well.
The next one is "constant magnet field", if you here because of questions too, you probably remember about Lorentz force, and now think - where is there perpendicular components? Good question, I don't know.
The third is electromagnetic wave, it actually has a perpendicular component, you can see it, it means, that the force there directs perpendicular to "previous line", it clear. Why do line curves by the next wave? Well, it could be intuitively understand, if you see the animation(link in the bot). By the way, if we assume that free electrons in metal would be fixed, and you will wave the wire, it will emit a em wave.
Considering, last case, if we put a charge in right or left, you understand it will move up-bottom. So, I think it explains in fundamental level the phenomena of induction. Lets go to macroscopic scales.
How does current flows
Well, there goes all confusing stuff, like voltage, potential difference, E.M.F, etc..
Lets consider the picture above. Okay, the AC wire in the bottom emits an em wave, the force actually directs parallel to wire near. So, now very attentively: electrons are uniquely distributed in wire - there at all, no places with higher or lower number of electrons. Now there occurs the force only in the bottom part of wire, and electrons in the bottom starts to move right or left.
Why do electrons in another parts of wire start to move? Well, I think it happens by the chain reaction:
Here goes specific questionS:
Is AC current in circuits without parallel connections the same in all points of wire(in one time frame)?
According to all stuff above, if it is true, explain this picture. Why current is maximum where voltage is minimum?
