Do I have it right that charges move from the area of higher potential to the lower potential. Would this be the reason why charges move away from the source towards the load? Is the source really the highest potential in an electrical system? Or is it both the highest and also the lowest potential? Charges regardless what we consider to be either positive or negative doesn't change what is happening in terms of their movement. Then we have the dynamics of not just the movement of charges but the movement of energy itself as it propagates. Energy propagates in a different vector. Energy does not seem to care about the direction of charges but seem to only care to go from the source to the load or is it that it also goes to the source as well, both out from the source and also and into the source? What about if you are standing at the load. There you see charges coming towards you from one side and energy is coming to you with it and going away from the other side, when going away what happens to the direction of propagation of energy.. are they less energy but still there but entering the source also or how does that work? Furthermore does energy really propagate by means of EM waves, EM oscillation? charges accelerating? If that be the case, a true DC system is the most ideal form of energy propagation as far as sufficiency of energy transfer goes, less loss, flat line, no oscillation. I don't think flat line implies infinite frequency. More question. When we see light coming out of the light bulb, such visible EM radiation is at very high frequency. 10¹⁴ Hz while the frequency entering it is 60 Hz. Does the element in the light bulb transform such low frequency into such high frequency instantly?

Hello, i wonder if someone could help with the wiring of this power board supply that takes in 240 volts and DC as output. As you can see it has (Ground, 230V, Common) as the three hook up and to the right of common is 4 hook up as the motor RPM. ( 1400, 1250, 1200, 1000) Of the four wires in my circuit panel in my house ( 2 black wires , 240 volts between them,wire A, and Wire B) 1 white wire, Wire C ( 120 volt with respect to the above two black wires.) 1 Bare copper wire , wire D ( no voltage between it and the above three wires). Which 3 of the above 4 wires ( A,B,C,D) should be plugged in to the three hook up on the board. See picture. Thank you.

If I understand how induction motor works is that in a single phase induction motor there are no rotating magnetic field. Of course the rotor rotates just fine if not as good or efficiently as the three phase motor. My main point here is that the rotor does not need to follow a single rotating field for it to rotate, it simply follows the fields on the coils of the stator which is basically hardly more than a pair. So my question is really this. Lets indulge in a thought experiment and assume that a rotating magnetic field in a 3 phase induction motor is just a misnomer. All we have is the three pair of coils and their localized alternating field.. How would the rotor behave? Would the oscilloscope show something other than is observed and would the location of rotor at any juncture be pointing somewhere else or freeze up or whatever other anomaly that may result..…. I am all ears.. Thank you very much in advance.

I was aware of the behavior of parallel wires. It was the reasoning that wasn't clear in my head. In regard to isolating charges. One way to find out I guess would be to use an electron gun and shoot a stream of electrons and another gun next to it and shoot another beam parallel and anti-parallel next to the first beam and see what happens. I suppose they can do it at CERN as well. I asked the gentleman in the YouTube if he would be able to run the experiment.

When I got up this morning all the answers have popped in my head this morning. I have it by golly. 1. Current moving through a wire creates circular magnetic field around the wire. Electrons one way and holes the other way. Both movement have the same magnetic field orientation from our frame of reference. 2. Another wire next to it in parallel will have the same magnetic field orientation so the two wires will be drawn towards each other. 3. If one wire is anti-parallel then the wires will repel because their magnetic fields do not have the same orientation. 4. If you shoot a beam of alike particles, as long as they are moving they will stay on track and keep going like baby ducks, such as" keep your ducks in a row", their magnetic fields are aligned. 5. If you shoot another beam of the same charge next to it, they will join together and keep on going. 6. If you shoot another beam of the same charge anti-parallel, the beams will repel because their magnetic fields will be opposite. 7. In a conductor such as copper, with a little EMF them valence electrons will get going in one direction with their magnetic fields aligned creating magnetic field around the wire. In an iron there are lots of electrons that are already aligned and if you run current through trillions of these atoms in one chunk, there comes a point that lots of electrons will align themselves and you get I guess what they call magnetic moment and you have a magnet. Depending on its make up and other things, determines the durability, temperature range etc and intensity of their magnetism. What do you think?

No it is not. I reworded and rephrased my question. I recognized how I should phrase my question after I read your reply to my previous post. Psychologically it is an unfinished business for me. I never finished and I couldn't finish school because they shoved more down my throat before I could truly swallow and understand the first bite. But If I went to school now, they will throw me out because I will bother everyone too much. Thanks to the internet. Now at least I have a chance to know how things behave but it is very difficult to understand why, save for certain things here and there. I am very confused about other matters as well. How parallel wires are attracted to each when the current flow in the same direction. and repel when the charges are anti parallel. Here is what I see in the first one the parallel one. The electrons in each wire have no magnetic field between them as they are in equal velocity, same direction and must look stationary to each other wire so there can only be electric repulsion between the electrons of each wire in relation to the other, the same goes with the holes of each wire in relation to the other. And in regard to our frame of reference The electric field within each wire is zero due to the total charges in each of the wire being equal. So now comes the question of relationship of electrons of one wire to the holes of the other and of course the electrons of the second wire to the holes of the first wire, in that relationship the charges are moving in opposite direction which I would think imply attraction because their magnetic field lines move in the same direction. Electrons moving one way is the same as holes moving the opposite way, both have the same magnetic field orientation. If holes come out of the screen it would be the same as electrons moving into the screen. Then there is the electric field between these. which would imply attraction as well. So in the first paragraph above there is repulsion between the stationary aspect of the charges of each wires. Magnetic field being zero and repulsion due to same electric charges assuming some net charges being opposite between each wire. Electrons repelling the electrons of the other wire and hole repelling the holes of the other wires. Total sum repulsion. In the second paragraph, things look in favor of attraction. So shouldn't all zero out. I don't know. Is the picture in my head all out of whack or is there some sense to it? It must be since the experiment shows the facts. Perphaps it is the explanation that has not been given to me correctly or I have misunderstood the concept and what I have said above is incorrect. I don't know if the charges in one wire view the other wire having zero sum electric field within that wire. Just because in our frame of reference there is no electric field inside a wire, maybe outside of it, I would think. These experiments are done with DC current, the attraction and repulsion of wires. So that is where I figured I just isolate the charges and I have began to realize that I have opened another kind of can of worms. Two same charge particles moving in parallel and anti parallel and see what happens. And two opposite charge particles moving in parallel and antiparticle and see what happen away from other influences. Things don't appear to be neat and straight forward.

You are the first human being that stayed on the topic. And thank you for your answer and awareness.

Imagine two streams of identical charges moving (anti-parallel, parallel and opposite in direction) in a vacuum away from any opposite charges influence like as in wires etc. The two streams are close enough to each other that both the magnetic field and electric field are present. In their own frame of reference, there is an electric field of repulsion and a magnetic field of attraction between the streams to my knowledge. 1. Will the charges stay parallel? 2. Will they get close and closer until? 3. Will they be repelled more and more? 4. ? Thank you.

To my knowledge here is magnetic field due to parallel moving charges ( conventional current) going opposite way as in a coil. Is there attractive force or repulsive force between the two? Imagine two streams of identical charges moving (anti-parallel, moving in parallel and opposite direction) in a vacuum. The two streams are close enough to each other that both the magnetic field and electric field are present. In their own frame of reference, there is an electric field of repulsion and a magnetic field of attraction. Which field will win? :-)

I have been confused about moving charges create circular magnetic fields around it. So if I have an electron moving into screen away from me, it will have a circular magnetic field that is clockwise. Another electron parallel to the above electron coming out of the screen towards me will have a circular magnetic field that is counterclockwise. So their magnetic field join instead of against each other. Do the charges repel as the consequence of their magnetic field joining? I assume the charges repel each other to my understanding. Which implies they prefer not have a joined magnetic field. What is missing in the picture that I have in my head? Thanks.
