How Inductors Work Within a Circuit - Inductance 

Good explanation. Still don't get it

Thanks! This was actually a VERY helpful video. As a beginner in this area of science, I am very grateful for the thorough explanation and example. Thank you.

Shite using DC as an example. AC should be used in these as the field changes much more involved

Inductive reactance The inductive reactance is expressed in ohms, and is useful to determine steady-state current values to sinusoidal voltage inputs. It is to be noted that though the value of the reactance is expressed in ohms, it was not obtained by computing a resistance, as of resistors. The current in the wires of an inductive circuit is a result of the applied field and an opposing coulomb electric field, which is set up by surface charge as a result of polarization of the inductor by the non-coulomb curly patterned electric field associated with the changing magnetic field due to the changing current and the current resulting thereof by applying the relation J = σE(NET) where E(NET) is the resultant field of the applied field and the coulomb electric field, and σ is the conductivity. For a comprehensive description of the mechanism of current lagging the voltage across an inductor see the book references below. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism. To know how they are unified visit this link matterandinteractions.org/articles-talks/ and view the article 'A unified treatment of electrostatics and circuits. B. Sherwood and R. Chabay, unpublished. (1999)' pdf.

great explanation... ive known of inductance and electromagnets, but never knew how to put them together in this sense. thanks alot :)

This helped me understand what and why we use inductance. Thanks.

This Video is GOLD!! thank you for taking the time!!

fantastic explanation.

The green arrows in this video are confusing. You should have used different colored arrows for the current due to the induced EMF vs. the DC source source current.

Having these visual explanations are very helpful 👌 🙏

Circuito é um caminho pra percorrer informações por corrente elétrica que conecta uma entrada por onde essa informação é introduzida e processada através de microprocessadores que comanda e coordena até um ponto em que ela se divide dando saída para o som e expandindo a imagem numa tela e todas retornam pra mesma placa de armazenamento,através de um conector na saída do circuito você consegue mover,transmitir e até mesmo modificar essas informações.

Useful video for students

2:14 inductor uses magnetic field to store energy.

The inductor stores energy in the magnetic field, not "in current". (2:20ish)

Why there was still has spark when switch open, the bulb would not consume?

What a wonderful and precise demo and explanation, I like it

Everything is sorted now with this topic ... Thanks a lot , Sir🙏

is the induced back emf goes to maximum point instantly, i mean when the switch is on? and then decrease with increasing flux?

Nice simplification, I'm still looking for an in depth explanation of the unique properties.

Beautiful man tanx alot for plain and simple

Good work. Thanks.

How did we know that the current reaches maximum value at '5' time constants , why not 4 or 6 , is it generalised result ?

by Marcus Tornea As current flows in a wire coil, it creates a magnetic field. This sudden appearance of magnetic field induces a secondary current according to Faraday's laws of electromagnetic induction, which flows in the opposite direction, as stated in Lenz's law. This is known more commonly as the "back EMF". Hope I helped.

True. That's why, in professional cabinets, like RCF, big inductors are used in passive crossovers. The more you raise volume, the more the iron core will induct & make the woofer sound louder & the impedance will be lower. Cheap crap cabinets use cheap crossovers to low cost, leading to mediocre sound quality.

i think in smooths current so not so strenuous on other components

Well now I’m confused. Another video says that inductors only effect AC voltage, but this video is demonstrating it with DC. So which is it?

what means rapidly, with what speed

Nice explanation, easy to understand.

Soo is the inductor and actual object or are there different type of inductor examples? Where are inductors use more?

Sir, what software do you work on

Why is the current changing (stated at 1:07) if the supply is a DC supply?

When to use capacitor and inductor in ckt.please let me know

Interesting and educative video.

Wow that makes a lot more sense. Stores amps as apposed to volts.

Best fucking video I have seen on inductance!

Is there a difference between inductor and solenoid

The north and south poles were the wrong way around.

Thanks

A quick note. Current is measured as the flow of electrons and holes, not just electrons.

Wonderful ! Thanks

my confusion on what is an inductor is solved by this video thank u so much

Good video sir, but inductance is defined as Flux linkage per unit current

Helped me a lot/

Whenever DC supply is given to coil it does not produce field

thanks

Hello could you test this software? Browse for circuit solver on the playstore!

The intonation or emphasis in the speech is a bit off at times. For example: "whereas a capacitor uses voltage to store *energy*, the inductor uses current". It should be: "whereas a capacitor uses *voltage* to store energy, the inductor uses current".

Thanks. But the flow of current is from positive to negative. do you explain why it is from -ve to +ve.

Thanks Frank

What happen to the BEMF completely over looked

Thos electrons are flowing the wrong way. Vacuum tubes, xray tubes, tv tubes, electrons leave the cathode and flow to the positive anode. In electroplating the cathode is - the anode that gets plated is +.

Bravo

It's just magnetic field. Not electromagnetic field.

Glad you presented the flow of electrons correctly. I cannot understand why the industry keeps hanging on to the ‘conventional’ explanation. Those doing so are promoting a falsehood. Really?!. When science clarifies the understand then change the presentation.

so why would anyone use a capacitor instead of an inductor (or vice versa) in a circuit for preventing voltage spikes?

1:51 comaprison with capacitor

so is this considered a flux capacitor, because it stores amperage

How can do current ?

👍

Isn't that kinda useless if you're using DC instead of AC?

solenoid

2:06 comparison with capacitor

What causes loss of power in an inductive circuit?

I don't understand. Not explain why,

But when flux just start to build up, i think lamp will light and then quickly dims

Don't you have the current going in the direction opposite it's typically depicted as going? You go from plus to minus, no?

Induction is not relevant in current without capacitance. You can have a DC source (dinamo motor for example) and run a light bulb as long as dinamo is turning.

what is l

Vim pelo Prof. Fernando

Good video, but the coil of wire does not have to be wrapped around a magnetic / metal core for the coiled wire to be an inductor! This is incorrect!!

Good video tutorial, but I still don't get it

This circute must is an AC circute

But why cant make transformer working?

Didn't follow the math very well, but I now realize that switching off my bedroom light used to come with the possibility of a house fire. Hmmmm.

You are wrong to say that the inductor retards the turning on of the bulb after the switch is closed. The light bulb will turn on as soon as the switch closes.

👌

Why - → + ????

the bulb should turn into bright red to show it's on

I need to do the science.

🙏🙏🌹🌹🌹🌹

I'm sorry but T is symbolic for the Period not the time constant. PLEASE USE TAU INSTEAD!!!

The missile know where it is....

Who stole the video, you, "Engineering Technology Simulation Learning Videos", or "Tech Maker"? I'm saying this because this exact video is also in: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dza3Vjxx8kU.html

An inducter shorts the curcuit if the main source is DC

J

Don't open an inductor circuit without creating a path do current flow. You'll cause considerable damage to the circuit. On this circuit, the switch will be damaged his contacts.

Great explanation, however that inductor will KICK like a STRONG HORSE when you OPEN the SWITCH, be Careful!!!!

Now in plain English

Take away. A capacitor uses voltage to store energy & an inductor uses current.

Who invested in physics? With the service woman? Of course you have not heard the right drill? Reverses the magnetic polarity in the drawing.

inductor was so confusing.. T_T

You lost me at "The purpose of an inductor..."

"The purpose of an inductor is to oppose any change in the magnitude of current..." but at the end of the video, current flows like hell and does not care about that damn inductor! :|

this a good example of worst the worst explanation..

No secrets revealed here Same petrol dollor education.

confusion with confusion. You don't understand how a coil works. You're confusing people who don't understand this yet!

This is an explanation for folks who already understand . This is not good for folks who need to learn the concepts.

crap animation shows the current going backwards ... it moves from plus to minus , not the other way around

you lost me at flux lines..

yeah ummm ... what in the actual fuck is going on ??
