- This video shows the operation of an electromagnetic induction. The coil consists of two windings of copper wire, "the primary coil 1, the secondary coil 2." The primary coil is composed of 220 turns of wire 0.40 mm. The secondary coil is composed of 120 turns of wire from 0.85 mm. The system supply voltage is 28-30 volts AC.
Explanation of the operation: in the spool of wood were wrapped two coils of copper wire separate between them. When in the central hole of the spool is inserted an iron core, the coil reacts by creating an electromagnetic field. Conversely, by exchanging the terminals of the coils, the electromagnetic force is canceled at the terminals of the wires. - วิทยาศาสตร์และเทคโนโลยี
That's magic. It's the only logical explanation I have.
Huh? Explaination?
@@priyanshunegi6844 it is not magic but a simple experiment of lass 0
That's pure science
@@brawltube4569 Nope. It's magic.
@@chicolofi i just realised you are right lol
We need demonstrations like these more and more 🤩!!! Thanks bro.
Fantastic demonstration to show the principal. Thank you.
Thanks for the video, i've been needing this.
I don't understand what is going on here? Do you have it plugged into a battery or 110ac?. And why is the power failing at a certain point wen it's hooked up a certain way?
Wait, so u use electricity to make magnet, then use the magnet to generate electricity?
just one question. where the hell did u find a 24v edison base bulb? or is this a standard 120 or 240v bulb and you have calculated its wattage at lower voltage?
what were those blue wires connected to?
Great demo. Thanks for sharing.
Awesome demo Thanks for sharing.
Pls explain the connections of primary & secondary coils and Guage wire in inner side?
Very cool. An electromagnetical switch including regulator.
awesome as always :)
I think something is not right in this experiment.
1. The bulb should only glow with the relative movement of a magnet wrt the coil.
2. The bulb should glow much bright when the movement of coil is moving in and out rapidly but here the bulb glow inspite of that magnet being still
3. Full circuit not visible hence nuclear experiment
4. That doesn't even look like a magnet...it looks like a iron rod imo
He says in the description "The system supply voltage is 28-30 volts AC" so he is applying (via the two black wires) an AC voltage of 28 to 30 VAC to the primary winding.
The statement in the description "When in the central hole of the spool is inserted an iron core, the coil reacts by creating an electromagnetic field" is not accurate. The moment he hooks up the 28 to 30 volts AC (VAC), the primary winding creates an electromagnet. There is, in fact, electromagnetic induction ONTO THE SECONDARY WINDING the moment he applies the 28 to 30VAC to the primary winding.
So - if the secondary already has an AC voltage in it, why does the light bulb only light up when the metal rod (which is not a magnet) is inserted?
Well, you just need to be a bit OBSERVANT to answer this question.
CAREFULLY NOTE that the brightness of the bulb gradually INCREASES as the rod is gradually inserted further inside the transformer.
This shows two things:
1) that the electromagnetic field is strengthened, incrementally, gradually, inside the coil, with the help of the metal rod
2) that the light bulb has a threshold of electromagnetic induction required *_IN THIS PARTICULAR TRANSFORMER_* to light up (brighter and brighter).
A physical analogy is this:
1) your car's electrical system requires a 12 volt battery
2) you let your car sit so long, the battery went flat and fell to 8 volts
3) you open the trunk and the trunk light does not light up, and you hook up your battery charger (why is the battery in the trunk? - because you have a mid-engine exotic car like a Lotus Evora GT or a Lotus Esprit V8 twin turbo)
4) you notice that with the battery charger charging up your car's battery, the light inside the trunk at first starts to glow dimly
5) then the trunk lamp glows brighter (you have the trunk lid open because you're charging the battery, remember)
6) finally, the trunk lamp is brightly lit and the battery is fully recharged to 12 volts
You go away thinking "I'm waiting for the Lotus Emira to come out next year anyway) well get in line
.
Very Very Nice Work !!!
excellent demo of multiple views. Hollow core versus Iron core. Using both windings at first connection but at second connection which wire is which that is not clear although the cancelation is expected.
A very nice video thnx :)
what do you think about the Heiss motor? can it work ?
Amazing experiment , in second part of your video , when the coil became Air Core , the brightness of bulb is increased , did you remember if the amp consuming is increased or decreased ?
Thanks for your sharing , and always your videos are amazing ,, forward ..
I ment @ 1:48 !
In all situations, when a light bulb turns on it absorbs current, even in this case.
wait the minute. this is not the right experiment im looking for., the one that powers a small light bulb when you quickly move the magnet in and out of the coil.
this seems to be powered by something else coming from that green wire ?
Neat video. :-). Good view count/rating considering you never said a word.
How would connect this...which mateial is use in this project...ND how we make this
Why have everybody written 'this is fake!' . This video is completely true and scientific. I'm a high school student and we learned the 'induction current' last week. It interested me and I want to try it at home, light a bulb without battery. So can you recommend me a more basic experiment video for who wants to do at home
Boy i am an IITian, studying in IIT KGP
You should carefully study a bit more. If the flux through the solenoid changes only then emf is generated. I hole you will understand
Bruh don't be discouragrd try it for yourself. Anyways this wasn't the basic experiment which this iitian kid is saying, it was something else. these students who go into iit mostly only know how to solve questions and high school theories anyways. No practical knowledge
Don’t trust on these IITians they just get into IIt and think that they are genius and others are fools but the reality is they just cram books formulas and techniques to solve questions and are almost unviable in practical things and this person is the best example as he must have crammed everything in textbook but hasn’t learned even a bit practical knowledge and unfortunately built an egoistic behaviour that he knows everything which has become resistive to his knowledge and made him dumb enough😂😂 This video is absolutely true and continue your studies and ignore these persons who think they are einstein
@@jan6428 and due to the emf produced the bulb is being lit .
What do you mean by "exchanging the terminals of the coils?"
what is the blue wire for? where is the other end connected to ? pls reply. Thanks.
The blue end wire is supplier.. may be battery....... but when he put that nuts inside the coil.... it light up the bulb....... it is how votage,current...control.... its a demonstration of how we control... high power and low
Can we create spark with that coil?
Thank you for all your electric video experiments!! Dont you stop being awesome! ;) I wonder why there is no laboratory which still does research in electricity??????
Matrixitookthe redpil Behind the scenes there is a lab :)
Electric Experiments Roobert33 Must be! ;) Do you have an facebook account?
That makes a good variac.
This is not how to teach. Only those who already understand Michael Faraday's experiments on induction will get anything at all from this. For newbies, the absence of a wide-angle view showing the 28-30Vac current being supplied, and the absence of any on-screen information simply creates more questions than answers. A waste of time.
Theres a diagram that transformer sir? And how its computed
this is a magnet ? or iron road?
Netflix: Are you still watching?
Someone's daughter: 1:23
very very good
primary and secondary winding how many gague nd how many turns plz mention
How many coils and how many turns per coil?
Explanation of how to make the same please?
Nice.
That- that's not even electromagnetic induction. As far as I know,
1. The bulb glows brighter only when the magnet is moving. It does not matter whether the magnet is inside or outside. When the magnet comes to rest, the bulb returns to it's original brightness.
2. The bulb should glow brighter when the magnet is moving faster.
Please correct me if I am wrong...
It's called the Flux change when the Flux change the circuit will generate induced electricity
will u pls give me the explanation of this?
@Abuzeid
Read the description of the video.
@Garry Fisher
They are two separate coils.
+Roobert33 j ai une question a vous poser comment vous faites ? pourriez vous me donner des explications
How you made this
Amazing demonstration!
I´d like to ask for your permission to use your video to create a video for my electromagnetism course. Would you mind? Thank you!
Ok.
This is how magnetic ballasts works,it limits the current!
Thank you for the training video. Robert and you can spend a exeperimental to reel under the influence of a magnetic field flew magnet coils and peresikal another coil and induces in it electricity. If you have the opportunity and time, gather yourself. More very interesting if you apply for a coil core static discharge will be drawn inside or not? Thanks! Sincerely Sergei 8
Сергей 8 On this issue I can not answer you because I do not have tried to do it. Of course to do something like that it takes time and study, but I'm not a scholar full. I do things electrical things that do not make me waste time ..
Thanks! I'm sorry to have spent your time! Sincerely Sergei 8
Bye :) I will look on you more videos and put Like!
Can u make a transformer like that with 12volts dc primary and secondary 22o volts..how its possible
Due to inductive coupling
Cool !
How to make this
0:03 how you teach us how to make that device please.
why are there so many wires connected to screws and where are they coming from ?

@@ElectricExperimentsRobert33 can u make one simple version? I remember seeingone in a science museum where each time the magnet is inserted a small led bulb lights up. I wanted to replicate that at home
@@SIDEKICKONTH-cam yes, I can do it, I already had this simpler thing in mind
@@ElectricExperimentsRobert33 NICE please make one for beginners to watch thanks
Can you make a video how to make it
i see your video but how make a electromagnetic Induction please uplode reledet new video i like video👍👍👍👍👍👍👍 just now
Had u put a magnet inside may be a small one
nice hi rob
if I have flashing led bulb ,how make 2 flashing led usd just this one ? any idea if You may thanks
I did not understand your question.
o ok i have 1 flashing led and like make conation secend to this first one so the bouth flash how i can do it with 12v dcc .I usd transformer and conect 2 thugader and is working / 2 flashing but when I conect same 2 tu my dcc track they don't flash any idea why??
woltar9 I do not know why it does not work, if I do not see your electrical system I can not help you, sorry.
ok i will make some short vid ok
Tuyet voi
It could also function as a variac unless you exceed a certain power and voltage :)
Where do you get those gloves ?
my2catsareblack In the shop for cleaning the house.
Cuanto dura el flujo eléctrico y qué potencia tiene????
El flujo eléctrico dura hasta que se conectan los cables eléctricos. No he medido el potencia.
Electric Experiments Roobert33 y cuantos minutos es aproximadamente y gracias por responderme saludos
Los minutos no cuentan, tiene poder hasta cuando, usted decide que desenchufar el cable de alimentación, y se detiene.
How are you going to apply this on a electric fan?
The system is not suitable for an electric fan.
Full ckt not visible
This is how the choke on an arc welder works, woopee dooooo

DC as AC uses just a single wire.
who upload this video?
I need this prototype.
Sangat bagus
Is it an insulated copper wire?
+Koi Erina They are copper wires covered with insulating glue ..
Ouncle are you professor in Oklahoma university? By the way
I am Italian and I am not a professor :)
Electric Experiments Roobert33 , it's okay Ouncle.. don't anger please keep calm and cool down
Is this project using an electric source?
Yes, 28-30 volts AC.
@@ElectricExperimentsRobert33 if 12volts source DC sir what is the input votlage and how it computed
Do you have the procedure to create this system??
Pls answer
@@ridhokartoni7847 is a simple electric transformer
wow u rock
why the iron core is moving like it was attracted by a magnet?
'coz the current flowing through the inductor coil IS producing a magnetic field, which is stronger inside the coil, along its axis, compared to that at either end... so the iron core is getting sucked in
Soung Nyi Nyi yes u r right
in detail
Read the description to find out more details. Weird
This is how the voltage.. or current is control.... i guess
This isn’t real the iron core must be in rotation to even get a little bit of light. Just placing an iron bolt in the middle of a non rotation art does not have energy put in so there’s no way light energy can be put out.
Kill, the video is 100% true, even the iron bolt creates magnetism with the current.
It's not the iron core...
It's a "transformer". Put ac in and the core is magnetic. But i don't know how the second one works, when you take the iron out🤔
@@badabing7820
In the second case, he connected the 2 inductor coils in series, such that they were cumulatively coupled. This caused the self-inductance of each coil to get added up with the mutual inductance between them, increasing the overall inductance of the circuit, which in turn increased the overall circuit impedance. Thus, the current in the circuit reduced, causing the bulb to glow dim. But, when he took the iron core out, the self inductance of each coil & also the mutual inductance between them, all reduced drastically, reducing the overall circuit inductance, & hence, reducing the overall circuit impedance... this caused the current in the circuit to rise, making the bulb glow bright.
@@adityasikdar Thanks for your very kind explanation. This is what I really want to know!!! OMG ~
Is that just copper and iron?
bodacias402 Yes :)
i want to get a iron ring wrapped around with copper around it i hear that make it superconductor will that keep whatever that is receiving energy cool without over heating?
bodacias402 the electromagnet will work, but for sure it warms..
higher the voltage?
La magnet ..?le fer et une bobine cuivre...non ..il y a qlqs choses cacher..
You have shown bulb connected at one end. Why don't you clearly show what you have connected at other end?
😂😂😂😂
The coils are powered by an outside source. The iron core gets inserted and then becomes an electromagnet. Hints all the wires. I think you people are looking at it the wrong way.
I'm the 100000 viewer.
Simply plug the bulb to the source to compare the brightness
But of course as you say .. but this video is just to show the function electromagnetism.
Ok.
(EN)In the first bolt increases the electromagnetic coupling. Second bolt increases inductance.
(RUS) В первом болт увеличивает электромагнитную связь. Во втором болт увеличивает индуктивность.
*****
Во втором подключении последовательно к обеим обмоткам, имеем просто дроссель. В первом, трансформатор.
Second connected in series to both windings have just choke. In the first transformer.
kya dikha rhe ho bhai ..jb tq magnet ka motion change karenge tb tq hi n emf enduced krega
+Deepak sharma
Wo magnet nhi tha... wo just ek iron ka core tha... supply AC tha, DC nhi... jiske liye emf induce hota rahega, irrespective of whether wo iron ka core move kar raha hae ya nhi... just ek transformer ki tarah
Explain kijie
Why are you wearing gloves?
coils are known to bite
@@aidanb.9043 So, if the wire was insulated, no need for gloves?
Thank you!
Make a new video on how to make it
some kind of resistor
Oh my god, is that all you need to create energy? Just a hex bolt! This is going to change the world and create free energy for everybody!
You're joking... right?
Well at least he's enthusiastic... And btw are you kinda obsessed with this video or something, the comment section is full with you're replies insulting people who are trying to understand whats going on in this video?
+Avokado Tropical
What 'insult' did you see in my reply to White Coyote? And what 'enthusiasm' did you see in his comment? I simply asked him whether he was joking, 'coz it seemed to me like he was kidding... that sounded like an insult to you? And it looks like yes, he indeed was simply joking... he wasn't serious. Everyone knows that there is no 'free energy' (if there is any such thing at all) involved in the pulling of a ferromagnetic object by an electromagnet. I dunno what 'enthusiasm' you're talking about... it was just a silly joke. Besides, if you write something stupid, like "this video is fake" and so on, it doesn't mean you're trying to learn or anything... it means you're stupid... calling something fake CONFIDENTLY, when you don't know much about it. It is like saying "this medicine doesn't cure this disease; the doctor is telling a lie", when you don't have adequate knowledge about the medicine or about the disease.
I will comment wherever I like... if you have a problem with that, I can't help it... so, better learn to deal with it. Even if I am obsessed with the video, do you have a problem? I am a little obsessed with electricity, tbh... just as you are probably obsessed with Tokyo Ghoul
whoa calm down :D
I did not say that you're directly insulting him, I said you're insulting people from the comment section, which is not really hard to see, calling people ignorant and stuff... Maybe you should calm a little and stop being too aggressive...
It isn't insulting... it is called calling a spade, a spade... I'm not calling them ignorant 'coz I want to insult them... I'm doing so 'coz they really are ignorant. They just come here and confidently accuse an honest man's work of being fake, citing flawed reasons... all thanks to their ignorance. Trying to learn something, and calling something fake confidently, are 2 completely different things.
Thanks for the advice, btw... I do get a little carried away sometimes. Maybe I should try to be a little less aggressive
interesting
nah, bro, this is pure fraud.
For sure you did not exchanged the terminals. You changed just one. So, for anything still work, you DO NOT have two SEPARATE coils. Otherwise you have no way to have any current! What you did was - supposedly - just connect the power source to one terminal in each coil - ending up just isolating the source. To induce current this way, only if you have very HIGH voltage in your green terminals.
It is transformer
please upload making video
Only mutual induction😂
thats not true! in order for the bulb to continue lighting there must be a constant changing of magnetic field.
+Louie Serrano
Ignoramus! The supply was *AC* and *not DC.* So, the magnetic field already WAS CHANGING CONSTANTLY, just like in case of a transformer. Go educate yourself!
Even then, he will still be above *your* pathetic level atleast... far far above
what just happened
