Question: Does electric energy propagate as electromagnetic waves and if that is the case, how? This is clearly not the same as propagating EM waves by an antenna whatsoever. If that was the case we wouldn't be filling the world with wires.
Some details about what I know about our electrical system below.
In AC power lines, electrons oscillate back and forth for miles and miles, if I understand this right the electrons move in the direction of electric field and the two are in sync. If this be the case then there must be electric field outside the wires and on the surface of the wire. The magnetic fields change direction orthogonally to the direction of the current and electric field and is also on the wire.
If I have that right, are there electromagnetic waves propagating from the wires every which way? Or is it linear, and if so which direction? Three-phase wires have certain distance from each other and typical home wirings are close to each other in one insulated solid configuration.
If this wave does exist, and the wires go on for miles, I just can't picture how this oscillation maybe and the result of EM waves. Is it at each point on the wire, knowing that the waves are ultra low frequency? Something does not add up in my head.
Also, the Poynting vector, being a cross product of the magnetic and electric field, does this mean that energy enters the conductors from outside the wires into the current carrying wires at all points inward orthogonal?
Furthermore, at the source of power generation, I assume EM waves exist with its own direction moving away in certain direction. Does it result in Poynting vector pointing outward at the source? (I am interpreting Poynting vector as being the energy density and its direction and that it is neither in the direction of electric or magnetic field nor is it in the direction of EM propagation, nor in the direction of current. That seem to cover all 3 dimensions. It doesn't sound right as there is no 4th dimension)
(Furthermore I am interpreting that most of the EM field is not far field but near-field and also not considering any back ward propagation towards the source due to all the other capacitance and inductive loads) And I assume that in essence it is pretty complicated phenomenon.
Energy entering the wires at all points, is the most difficult for me to picture if that is the case. At the source I assume EM waves leave into the empty space as is energy density flux Poynting vector, they point away leaving the source into empty space, and the same for the load; energy flux pointing out leaving the load.
And the energy that enters the wires may not necessarily be the same energy the leaves the source and the same with the energy that leaves the load. To my understanding, they don't have to be the same energy. So how on earth does the communication takes place?
And at last, how does the energy propagate from the source to the load if not in some way by means of EM propagation? The energy certainly moves far faster than the electrons vibrating back and forth and in one direction too from the source to the load.
On another note, I do not have the slightest idea how energy moves in DC circuit. My question comes from the understanding that energy is delivered by means of photons/electromagnetic waves when it comes to currents, electricity phenomenon.
There is something I am surely missing. I can only think that this energy moving from the source to the load is not in the form of radiation or propagation which can not be in the direction of current either.
I hope I made some sense and my question is clear at least somewhat. Most likely, I will be asked to edit. It will end up the same long narrative, and will end up pieced together bit by bit deffered instead of all in one place.
Thank you in advance.
