Signature Edits I’m not sure the there is any way around the copper coils and magnets but the method in which we turn these generator turbines is insane. Our first idea has been one of the best. Use falling water. But then the next 2 are out there. 1.) Let’s dig up Old dinosaurs and plants from millions of years ago, light it on fire and boil a big pot of water to create steam. The steam will turn the turbine. 2) If we can split a uranium atom we can release a lot of heat to boil a big pot of water. The steam will turn the turbine. So let me get this straight you split the atom to boil a pot of water. Way to go

Oliver Heaviside is the most underrated scientist ever. In school they teach us about Galvano, Ampere, Tesla and so on, but never Heaviside. Oliver Heaviside was an autodidact (self-taught) mathematician and physicist. He coined all the terms used in AC circuit analysis, he invented vector calculus and his work changed telecommunications. Fun fact: since he wasnt formally educated, he was in conflict with the scientific establishment his whole life
@@stuckonearth4967 It's not just Heavyside. Elon Musk naming his company Tesla may be the only reason we know that name. The masters tried to sweep him under the rug and discredit him too. The crime is not being self taught it's anything that redistributes power or wealth from the masters. This goes back to ancient times and the story of Prometheus who stole fire from the Gods in 500 BC. Zeues crucified him to rock and had an eagle eat out his liver, which would regenerate so Prometheus could be tortured again the next day at infinitum. The moral of the story is when you discover something and don't bring the current powers that be with you unveil it the power you unleash may become so imbalanced that it lashes out against you. So unfortunately advancements will probably have to include big oil and the most polluting companies or they may react so sharply against that new scientist, that he will join Heavyside, Tesla, and Prometheus.
This has to be in the top 5 channels on youtube. Incredible explanations and hysterical commentary. I think I've laughed to tears at least three times watching this channel.
Your videos should be mandatory in school as an introduction to a new subject, they usually make it SO much easier to understand a course. Many teachers know the subject, but they can't teach it. Your videos are usually "reference level" in both cases...

Keep this up dude, you not only matter so much to me as someone that was screwed out of a proper formal education in the sciences, but I pass this stuff to my (at the moment:) 9yo nephew and use it to explain things ostensibly "beyond" his ken. You're making a huge fucking difference, man, keep going, even though it won't be immediately visible. You're not just making my 30yo ass smarter, but I use your material to encourage kids I know.

I think the important thing that people often miss is that when current in drawn from the voltage source (so power), a torque is created so that it impedes the rotation. So we don't only have to make spin the rotor "once" to give it momentum, but apply a constant power at least as much as the drawn electric power.
I don't think anyone misses that. If you could spin a rotor with one push and it ran forever and ever having a perpetual motion machine there would be no issues regarding power or the climate. Perpetual motion machines aren't even really pursued anymore except as UA-cam click bait. All the solutions for clean renewable energy have been invented. Will we have the resolve to implement them or will we go down in history as the monsters that set in motion the destruction of all life on Earth. Knowing full well it was happening and how to stop it, but did nothing.
@@anthonypape6862 Your'e in the good side but trust me, almost 99% non tech would imagine that it might be possible to retrieve more energy (and especially because they don't really feel what "torque" is but only speed). I have a vid with exactly this point explained, it has +2M views, and it's not sufficient to convince everyone!
@@ScienceAsylum how is the valence of the conductive metal refilled after electricity flows though it? i realize it they are lost and contributed one to another in a flow of electrons down a wire but somethings has to refill the valence shell electron in the original atoms that was lost. Anyone know??
@@Acuraintegraman1 It doesn't _need_ to be refilled because it's a closed circuit. Imagine a closed pipe system where water never leaves. Do you need to refill it with water?
I wish I had discovered this channel years ago! Absolutely profound insight along with an impactful delivery that makes us viewers engaged! WELL DONE SIR!
Pushing a wire side ways in a magnectic field should cause current, brilliant and very clearly explained. Now I know exactly how the relationship between current and magnetism works, great video...
3:30 It's also worth to mention that when there is something connected drawing current from the generator, it gets harder to spin (I guess you'll cover Lenz's Law in a future video). That's why infinity energy generators don't work. When there's no current flowing, all the force you apply is turn into motion, and since nothing is consuming energy, the coil would continue to rotate indefinitely, if there was no losses due to friction and drag. However when something is connected, creating an electrical circuit, part of the kinectic energy of the coil is turned into electrical energy. Thus if the torque applied is constant, the angular speed of the coil will reduce, or conversely, to make the speed constant, a higher torque is needed.
This a good point and something that might be worth doing a solo video on. I remember we did experiments like this in physics class. Let a pendulum swing through a magnetic field and it swings normally. Replace the head of the pendulum with something conductive like copper and the pendulum swinging stops really quickly, the breaking action is really evident. What's going on is that the magnetic field induces a current within the copper, little electrical loops. Because this takes energy, the energy has to come from the motion of the pendulum. Hence the pendulum stops moving very quickly because those current loops are actually using up a lot of energy. The point of the lesson was the same as yours: perpetual motion energy-making machines don't work. That energy really has to come from somewhere, and there ain't no free lunch.
@urmthrwan Yes, in theory it would be possible if you also eliminate the mechanical losses (friction and drag). It makes sense considering that the power is given by the product of the voltage across a device by the current passing through it: P = V x I. Usually, the power is zero if there's no load, meaning there's no current regardless of the voltage generated. In this setup though, there would be no power dissipated because there would be no voltage drop between the ends of the coil, regardless of the current passing through it, so the power equation becomes zero too. I don't see any practical application of this kind of generator though.
Have to be honest, first time watching one of your videos I felt like they was meant to be just for kids, but now I really enjoy each one of them. They are explained so well, in such details without all that misleadings examples that are used to supposedly help us understand. I hope you keep doing it for a long time and I expect to be one of your patreons soon. I think I may help you with spanish subtitles so I could recommend this channel to more people. Thanks for your work!
I just hope UA-cam recommends your videos like it does for other physic channels as I believe you should have over a million subscribers already. Thanks for the videos nevertheless. You are awesome
“ To the time line!!” ;) Another rather rather g o o d piece of edutainment. It’s the balance of competence and humor that we , your fan community are unable to resist.
Thank you, this is what I wanted to know! I kept trying to look up how rotational energy is actually converted into electrical energy, but all the results and other UA-cam videos just kept skipping over the electromagnetism part! Y'know, the part that actually converts the mechanical energy to electric energy. This is such a fantastic video!
That's what Steampunk is all about. It's an alternate history fiction that explores what our modern world would look like, if electricity were never discovered.
6:20 We don't always turn coils. Usually the coils are fixed to the stator and the rotor has DC excitation to cause the change in magnetic flux but the same thing really
Wonderful explanation! This channel is the Oliver Heaviside of UA-cam. On a positive note, the improved YT algorithm has actually provided me with something useful.
Thank you, your video explained it really well, i love how you made it clear that magnetic induction/spinning coils around is the actual source of energy. I was really confused trying to understand how Nuclear Powerplants work
The original source of our energy is the Sun. All we do is convert energy to a more convenient type. We have never made or destroyed energy. It just is, and it's free in the raw state as when Sun bathing. All conversion is costly and has inefficiencies. Sun to electricity by photovoltaic panels, wind to mechanical, to generation, fuel to mechanical to generation.
@@krishabm1... I think you have to run a magnet through a coil. I don't think it works with bread you want to toast. I am hungry, I will try it and I'll let you know if using my toaster reduces my electricity bill.
You make science interesting in a way that would have taught me a LOT more in the science classes I was FORCED to take... and for a LOT less money. Being crazy is part of it... all the BEST people are, you know :))
Usually it's the magnet that spins, and not the coils. It's easier to extract power from stationary coils. The magnetic field can be created by a spinning coil, but it operates at a lower voltage which can be passed into the rotor by slip rings or a transformer
Question not about electricity but black holes: An old video mentions that there is infinite time dilation at the event horizon; a distant observer would never see a falling clone cross the event horizon. So how to black holes feed or merge, and how can we see evidence of it, if the time dilation for objects falling into a black hole is so severe that it never "happens" for us?
For a distant observer, it doesn't actually matter if stuff crosses the horizon. If it's close, it's still adding to the mass located in that general area.
In calculus I always heard about the "Heaviside step function" and I honestly thought it was "heavy-side" like heavy vs light and had something to do with taking the value of 1 rather than 0 at 0 until I quite recently (but not today) learned there was a physicist named "Heaviside" who invented electromagnetism and vector calculus.
Taylor Polynomials is another interesting coincidence where the mathematician's name describes the concept he contributed to mathematics. A Taylor polynomial is tailored to match the function.

Omg, i am almost tearing.. It was hard for me to get a full understanding of the magnetic induction for 2 months.. And u just simplified everything for me in less than 7 minutes.. Thank you so much ❤️❤️
Voltage is actually the potential for charges like electrons in the electric field. A potential is always the difference of energy of the particle at a point compared to the energy at a reference point diveded by the charge itself. So if you multiply the voltage (or the potential) at a point by a charge you get its energy at this point. Or in other words the higher the voltage, the higher is the energy of charge at that voltage.
By energy i mean the potential energy und note that you dont always divide by the charge. For example there is also a potential for the gravitational field which is the difference of potential energy divided by the mass. So in general the potential of a force field in physics is the potential energy divided by the quantity which causes the force. The cause of the force in the electric field is the charge.
If I am not mistaken, in hydro power plants and probably in other generators too, the coils are static. It's electromagnets that rotate alternating south and north along the coils that go around the rotor.
Maxwell built a generator that spun continuously once started that produced a voltage at the outer rim of a round copper plate sandwiched between 2 ring magnets and drove a generator which also produced an electrical output but he never pursued it. In the 1980s Bruce de Palma perfected that setup at got 10 kv from that similar setup and he pursued it and died shortly after after releasing his plans to the world. Seems like a generator will also produce electricity if the magnet and copper are spinning together. Good video keep up the good work.
To through internet wifi in universe to be abundant then dark matter and dark energy so that universe doesn't collapse internet wifi in light year fast
The microphone you talk into converts a metal plate's motion into electricity. A magnet provides the field and a coil collects the current. Vibrations from your voice make the mic's plate vibrate, same in guitar pickups where the strings replace the plate. Scream close to a guitar string, and the amp will actually project your voice.
Just wanted to throw some inconsistent encouragement your way. I'm not a scientist, or use what you teach in any way. I'm a meditation teacher. But as a teacher I recognize that you do more than just entertain us or help students pass tests. You are following a passion, discussing the nature of the universe. And despite the fact that it may not bring you wealth or much utility, it adds something important to the question of what it means to be human. You inspire, guide, and provide a positive example of humanness. You've touched hundreds of thousands of minds if not millions. You done good kid. :-) Keep it up. Much Love!
The changing direction of current means that the electrons don't move very much. What's moving is the energy they carry. You can think of it as a wave. If you have a wave pulse travelling a rope for example, the rope itself doesn't move forward (only up and down), what does move forward is the energy pulse.
AC _doesn't_ flow from one point to another. The charge never goes anywhere.... but it doesn't have to. You just have to get the _energy_ to go places. Whether the charge goes places or not is irrelevant.
Technically it will also depend on the kind of load it's connected to the AC power supply, some loads, called reactive loads, don't use the electric energy generated, they basically store the energy and then give it back to the generator, so in the case of an ideal reactive load, there would be no energy transfer. Using the wave analogy, it would be like a stationary wave or an harmonic oscillator.
one crazy question nick ! imagine if we isolate a black hole ....and start "feeding" ELECTRON ONLY. what will happen if we continue to feed..also consider that black hole also SPIN. will it produce magnetic field also?
I believe it should be plausible. However, getting a black hole charged to the extent that it produces a magnetic field great enough to be used from the distances we can reach would require an immense quantity of charged particles to be sent within it. Nonetheless, as had been said above, they already do have a significant magnetic field.
Yep. By the way i forgot to add my answer. If you threw electrons into a accretion (sorry if spellings arent correct) disk, then those electrons will produce a strong magnetic field. But for a blackhole to have a magnetic field, it must have a charge.schwarzschild bhs and uncharged kerr blackholes wouldnt do that.
When you (we) take a walk down Main Street one can only wonder how ingenious the spirit of us human beings can be. This is not the least reason why I don’t miss a single vid of N.L. and the fabulous Clone Team.
Sir,you please explain the mechanism of producing electric current from magnetic field with a diagram. I have read many a times this,but still I cannot understand.
This is extremely interesting. And well explained. Thank you!!! Now, how do you take the energy from the spinning coil and turn it into electricity we can plug into?

I’m in EE right now, and I would love if you made a video on the relativistic explanation of electrodynamics. Love your videos btw !
I was curious as to how electricity made stuff work, now I'm watching this at 4 am, learned a lot though
Then this one is going to blow your mind: ua-cam.com/video/C7tQJ42nGno/v-deo.html
Omg, i am almost tearing..
It was hard for me to get a full understanding of the magnetic induction for 2 months.. And u just simplified everything for me in less than 7 minutes.. Thank you so much ❤️❤️
Glad I could help! 🤓
Hello crazy.your videos are best
Pls can u make a video explaining what voltage actually is ?!?!?! 🤔🤔🤔
Voltage is actually the potential for charges like electrons in the electric field. A potential is always the difference of energy of the particle at a point compared to the energy at a reference point diveded by the charge itself. So if you multiply the voltage (or the potential) at a point by a charge you get its energy at this point. Or in other words the higher the voltage, the higher is the energy of charge at that voltage.
By energy i mean the potential energy und note that you dont always divide by the charge. For example there is also a potential for the gravitational field which is the difference of potential energy divided by the mass. So in general the potential of a force field in physics is the potential energy divided by the quantity which causes the force. The cause of the force in the electric field is the charge.

Really amazing to see how the causality works in the situations at the very fundamental level.
Great video!
"WORK IT! I need a glass of water..." 🤣😂👌
If I am not mistaken, in hydro power plants and probably in other generators too, the coils are static. It's electromagnets that rotate alternating south and north along the coils that go around the rotor.
How long does it take you to upload please more
I upload twice per month. It's best I can do. These videos take forever.
@@ScienceAsylum thanks for the amazing content
Maxwell built a generator that spun continuously once started that produced a voltage at the outer rim of a round copper plate sandwiched between 2 ring magnets and drove a generator which also produced an electrical output but he never pursued it. In the 1980s Bruce de Palma perfected that setup at got 10 kv from that similar setup and he pursued it and died shortly after after releasing his plans to the world. Seems like a generator will also produce electricity if the magnet and copper are spinning together. Good video keep up the good work.

Finally someone that makes this clear and simple! Thank you mate, keep on going, your channel is amazing!
you deserve more, your videos are interesting and easy to understand!, especially for beginners like me =]].
My Teacher used your videos for examples. You’re a great teacher.
That's great! I love to hear when my videos are used in classrooms.
I'm a D.A.R.E. instructor and I use your videos all the time in class!! ...Naw just fuckin with ya...
To through internet wifi in universe to be abundant then dark matter and dark energy so that universe doesn't collapse internet wifi in light year fast
I started my iPad, and your video started on its own...
Your clone must’ve pushed play...
Thank you, pushing clone.
I watched this video with no sound and captions.... Nick’s voice resonated in my mind all long the video, even the sound effects... it’s crazy!!!
0:42 “you know what’s coming”
The microphone you talk into converts a metal plate's motion into electricity. A magnet provides the field and a coil collects the current. Vibrations from your voice make the mic's plate vibrate, same in guitar pickups where the strings replace the plate. Scream close to a guitar string, and the amp will actually project your voice.
Indeed!
i understood great
Me too. Me now know good.
One of your best video! Congratulations.
TIL: Most power plants are just a very very large water boiler.
Fact.
Just wanted to throw some inconsistent encouragement your way. I'm not a scientist, or use what you teach in any way. I'm a meditation teacher. But as a teacher I recognize that you do more than just entertain us or help students pass tests. You are following a passion, discussing the nature of the universe. And despite the fact that it may not bring you wealth or much utility, it adds something important to the question of what it means to be human. You inspire, guide, and provide a positive example of humanness. You've touched hundreds of thousands of minds if not millions. You done good kid. :-) Keep it up. Much Love!
Thanks!
I wish you were my school teacher
How does ac work,if the direction of current changes every time then how does it flow from 1 point to other i don't understand?
The changing direction of current means that the electrons don't move very much. What's moving is the energy they carry. You can think of it as a wave. If you have a wave pulse travelling a rope for example, the rope itself doesn't move forward (only up and down), what does move forward is the energy pulse.
AC _doesn't_ flow from one point to another. The charge never goes anywhere.... but it doesn't have to. You just have to get the _energy_ to go places. Whether the charge goes places or not is irrelevant.
Technically it will also depend on the kind of load it's connected to the AC power supply, some loads, called reactive loads, don't use the electric energy generated, they basically store the energy and then give it back to the generator, so in the case of an ideal reactive load, there would be no energy transfer. Using the wave analogy, it would be like a stationary wave or an harmonic oscillator.
My next video is going to help clear a lot of this up.
I'm like question clone. Pointing out the details. Curious.... Lol
The notification of this video magnetised me to the point I started radiating with excitement. So, here I am.
one crazy question nick ! imagine if we isolate a black hole ....and start "feeding" ELECTRON ONLY. what will happen if we continue to feed..also consider that black hole also SPIN. will it produce magnetic field also?
Black Holes do have magnetic fields
If they have a charge 👆
@@Private_Duck
If they have mostly electrons, they do have a charge.
I believe it should be plausible. However, getting a black hole charged to the extent that it produces a magnetic field great enough to be used from the distances we can reach would require an immense quantity of charged particles to be sent within it. Nonetheless, as had been said above, they already do have a significant magnetic field.
Yep.
By the way i forgot to add my answer.
If you threw electrons into a accretion (sorry if spellings arent correct) disk, then those electrons will produce a strong magnetic field.
But for a blackhole to have a magnetic field, it must have a charge.schwarzschild bhs and uncharged kerr blackholes wouldnt do that.
Another great video--sorry it took so long for me to watch this one. Looking forward to the next. :)
That next one is going to be mind blowing. Also, Ben, you're under no obligation to watch my videos ;-) There's no pressure here.
Yes more "to the time line!" haha
Awesome video! I learned a lot (as usual). Please keep making videos
1:31 they look so cute from the side view 🤗
Anyone agree?
The clones are the best
Hands down the most underrated channel.
Anybody here now??
When you (we) take a walk down Main Street one can only wonder how ingenious the spirit of us human beings can be. This is not the least reason why I don’t miss a single vid of N.L. and the fabulous Clone Team.
Who’s here from Dr. Stone ?
Sir,you please explain the mechanism of producing electric current from magnetic field with a diagram. I have read many a times this,but still I cannot understand.
had to watch this for physics homework, wasn't looking forward to it, but I was pleasantly surprised. Definitely getting a sub for this
Strength are the guys who make things funny and reduce their increase in ado about saying something,Keep it up bro,Well done
This is extremely interesting. And well explained. Thank you!!! Now, how do you take the energy from the spinning coil and turn it into electricity we can plug into?
As Magneto shouted out in X-Men 97 episode 2, "Electricity and Magnetism are intimately acquainted." ❤
Nice, but we're not talking Marvel, we're talking d.c. Get it? D.c.
And electricity converts to energy, and where it all begins. Thanks for the explanation. I’ve got better understanding now.
This was the best science video I have seen. So entertaining! 😲
Thank you for helping me better understand that Dr. Stone episode
I love your videos Nick. When will your topic of electrodynamics get over. I mean I love this topic, but I want to learn something new too.... Letting everything aside, I just love your videos!!
We'll be taking a break from it soon. I'm getting sick of it too. I want to talk about other things now.
Nick Lucid, you are the best teacher i ever saw and these videolessons are so exeptionally clear, i wish you where my teacher in my school. A pity i am dutch, but the school where you work shall and will without doubt deliver science students noticable above the average, in number ánd level. You are unique on youtube, thats for sure!
Yet, none of them ever wanted to hire me full-time...
They need to show your videos in schools. Make Science Fun :)
Awesome stuff !
The Ms. Eliot edit was gold!! 🔥🔥💯
Great video. You should have also covered the sources of magnetism in the various practical power generation cases (e.g. electromagnets, permanent magnets, hybrid setup etc.)
the best lessons are those that use parables, nicee teaching method
