What do you guys think of Veritasium's videos on this topic? They made a pretty big splash on YT. So is he right?

>on YT
That's like saying the LHC found a 1.5sigma discrepancy
I don't know what that means. Look, I'm a science brainlet, but I was just wondering what the best way is to explain electricity to a layman like myself.
It seems he was merely stating that, while electricity may flow /along/ wires, and is /associated/ with the movement of electrons, it also creates an electromagnetic field that /transcends/ the wires...is that the gist of it?
the jist is that electrons are constantly bound to the electromagnetic field
I wouldnt say the field transcends, its very discreet, think of a magnet and how its force has a certain range and polarity. What determines how much energy the fields will induce in a conductor is the exact same phenomenon. Key point: move electrons around and then they emit a field.
>I don't know what that means.
Don't feel bad, they don't know how magnets work either.
>but I was just wondering what the best way is to explain electricity to a layman like myself.
"electricity" is a perfectly crafted psychosis of a power distribution system for laymen such as yourself that utilizes magnets passing over archforms of dielectrics to create "hertzian waveforms".
>It seems he was merely stating that, while electricity may flow /along/ wires, and is /associated/ with the movement of electrons, it also creates an electromagnetic field that /transcends/ the wires...is that the gist of it?
He finally figured out that the field is indeed not in the wires. Any electrical engineer could have told you this.
>Key point: move electrons around and then they emit a field.
Like how my hand "emits water" when it splashes a pond to make waves right?
Magnetic reluctance. It depends on the geometry of the wire(s!).
>Any electrical engineer could have told you this.
the failure of the engineers to discern between lumped model and reality was the point of the video. it was quite embarrassing to say the least.
checked and yes. But i think this is a broader problem with how science engineering and tech are taught: people believe the models are real, rather than treating models as systematised knowledge. The whole "electricity flows in wires" here for example.
john krakauer discusses this so-called M^3 mayhem at length with sam harris here:
I'd say this is a problem in how engineering is taught. Too much emphasis on model and less on what really happens, so the engineer thinks the model is the real thing.
>>Key point: move electrons around and then they emit a field.
>Like how my hand "emits water" when it splashes a pond to make waves right?
No, electrons and electromagnetic fields don't exist in a medium like water. They are their own medium, hence thinking about EM waves in a water sense doesn't reflect what we see in reality.
>They are their own medium, hence thinking about EM waves in a water sense doesn't reflect what we see in reality.
>waves really aren't a thing
>the medium is disturbed
>this is traveling when the medium is "already there"

Lol, electrical engineers don't use any of the quantum bullshit because it has no basis in reality to what they're working with. They hook a wire from point a to b and the rest is pic related. Anyone of them that's worked at a substation, generator or as a lineman knows full well the energy isn't in the damn wires.
really aren't a thing
>>the medium is disturbed
>>this is traveling when the medium is "already there"
photons are real, moron
>Lol, electrical engineers don't use any of the quantum bullshit because it has no basis in reality to what they're working with
its not quantum but standard EM.
Then why does a small wire carry less current?
less surface area
not sure what op is about but long ago i heard a theory is that electrons do not "travel though the inside of the wire" like water in a hose.
But instead the electrons "move" along the outer surface of the wire
Okay I make very good wires sirs only half the copper pls to buy this and put it on transmission lines okay sirs very good deal
>he doesn't know what stranded cable is
NGMI
Electron make wavey in the air and it transfer energy.
bullshit
he owned you science denying chuds with his follow up video btw
You mean the video where he admitted he was wrong and then made more incorrect claims but the other content creators didn't want to hurt his ego?
I report any veritasium videos that come in my feed as misinformation and I'm trying to get Google to ad disclaimers like they do for flat earth.
I was involved with that...he tried it with the wires at 1m distance and couldn't get any reading...we had to move that fricking thing closer like 5 times before he got the result he was looking for.
>Media israelite says everyone is wrong
>everybody thinks light makes shadows
>but he knows better
>shadows actually make light
>presents this conclusion as a huge, unquestionable breakthrough
>cult of personality laps it up
Nothing to see here. Just israelites doing typical israelite things.
It showed to the world what engineers are truly like.
He framed the experiment in a ridiculous way to force a contrarian answer to the question...and did so in a way that normies actually understand less than they did before watching the video.
To everyone in this thread and Veritasium as well.
Why does touching the copper in the lead wire shock me, but if I hover my hand over the exposed wire, I won't get shocked? Even though according to Faraday's law of induction, a conductor (my hand) cuts through a magnetic field, therefore current should be generated. It should be shocked in the same way as touching it, if the electric field is what generates the current. Or is it that the strength of fields dissipates the further you move from the centre of field?
If this is the case, then the electric field is perpendicular to the copper wire. That's just my view on it
Depending on what kind of sparky juice you're dealing with it very well could arc over to you even from a large distance. Have you perhaps heard of lightning?
Dont worry, in veritasiums latest video he lied completely about his experiment, its why he cut it really short and put it at the end.
He shows himself inducing 5v 20ma or something like that before the full 24v 20a reaches his resistor and scope. Then he cuts to him holding an led powered by a battery saying that 5v 20ma is enough to light it, and that makes him right. However in reality had he set up the experiment with the LED in the circuit, it would have exploded before lighting due to the high voltage and current across it.
The field is perpendicular to conductors but its also parallel and tangent. Its really a 3d torus that interacts with itself depending on the conductors shape and the dielectrics around it. I think veritasium is being a troll on purpose because he already knows all of this, and wants to bring more attention to the fields instead of having all of his normie npc subscribers only thinking about conductors.
He's literally just talking about magnetic fields which are irrelevant when it comes to electricity transmisson because wireless electricity would be viable otherwise.
yes, this is common knowledge
t. EE
Energy does flow in wires, electrons just aint the medium.
What is? Photons? Isn't that the essence of QED?
He's right in the "you never touch anything because atoms don't touch" sense.
