+Roobert33 j ai une question a vous poser comment vous faites ? pourriez vous me donner des explications

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

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 .

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 .

I ment @ 1:48 !

In all situations, when a light bulb turns on it absorbs current, even in this case.

Ok.

It's called the Flux change when the Flux change the circuit will generate induced electricity

Electric Experiments Roobert33 Must be! ;) Do you have an facebook account?

Due to inductive coupling

my2catsareblack In the shop for cleaning the house.

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.

@@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

@@SIDEKICKONKZfaq yes, I can do it, I already had this simpler thing in mind

@@ElectricExperimentsRobert33 NICE please make one for beginners to watch thanks

The system is not suitable for an electric fan.

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

DC as AC uses just a single wire.

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!

Electric Experiments Roobert33 , it's okay Ouncle.. don't anger please keep calm and cool down

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.

'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

Pls answer

@@ridhokartoni7847 is a simple electric transformer

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

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 ~

😂😂😂😂

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.

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?

+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

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.

coils are known to bite

@@aidanb.9043 So, if the wire was insulated, no need for gloves? Thank you!

+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

Ya is clearly CGI. Nasa at it again.
