Ok, thank you.

Thank you for the reference.

-Separated charges have incoming or outgoing radial field lines. -Free charges in a conductor do not have them due to the cancellation with the field of the positive nuclei to which they are bound. -Both radiate when accelerated. It means that the charge of the poles generates the induction...

The most common way to determine the fields generated by a distribution of charge and current is through their electric and magnetic potentials. It is interesting, or so it seems to me, to interpret the results from the point of view of Maxwell's equations. For example, from a separated electric...

Thank you very much.

The fact that I get more questions than answers makes me think that I have not asked a well-thought-out question. I think I'd better ask a new question with a different approach. Thank you all.

I have read a lot before asking but I could not extract an answer, this has led me to think that it is a subtle question, so I chose level “A”, but possibly I have been wrong, I apologize. I am not asking for a mathematical development although I know that mathematics is the language of physics...

I am sorry, I have expressed myself badly. I am only asking about the electric field of radiation. It is clear that the magnetic field comes from the current, my doubt is the origin of the electrical part.

In various books, blogs, etc., the Hertz dipole radiation is presented and visualized as field lines that lose their link to the pole charges due to the retarded value of the fields at distant points, lines that close on themselves and jump into space as waves. From this it can be deduced that...

fresh_42, Bosko, my question is perfectly answered, thank you very much.

No, I wish, I'm 60 years old.:smile: Thank you Perok for your answer.

Can a vector subspace have the same dimension as the space it is part of? If so, can such a subspace have a Cartesian equation? if so, can you give an example. Thanks in advance;

DaveE, Baluncore, tech99, thank you very much for your help. I incorporate the suggestions into my understanding process. Ok, I understand that some phenomena present simultaneous manifestations without being able to establish cause-effect relationships between them. If I understand correctly...

Thank you very much for your answer. Yes, I consider the ac circuit as a transmission line. The equivalent circuit to the line with inductors and capacitors is useful to obtain (telegrapher's) equations of V and I as a function of the line parameters, i.e. to forget about fields and charges, but...

Thank you very much for your answer. I appreciate that the explanation includes both the fields and V-I. Does this mean that an electric field line (to simplify) advances through the dielectric "drawing", with its perpendicular force, free charges from the conductor to the surface and then...
