Self Inductance of Inductors & Coils - Solenoids & Toroids - Physics

This physics video tutorial provides a basic introduction into the self inductance of inductors and coils such as solenoids and toroids. This video explains how to calculate the induced emf generated when the current is changing inside of an inductor. It also explains how to calculate the self inductance of a solenoid and the inductance of a toroidal solenoid. This video contains plenty of examples and practice problems.

You made it so simple and easy to understand. I love the simplicity of your teaching. 👍

[@samuelonyango-xt6le]

This is great sir, You are assisting many across the world!

[@jefflee9201]

Honest to god you make everything make fucking sense again. I hope you are having the best time of your life right now

[@ahmadabdel9114]

Thank you, I really do appreciate what you do

[@bradyrieger]

@Domenic Steenland This is rock bottom scamming

[@Lecommandant_camroun]

Not just you........ Jesus loves you, repent and God bless!!

[@bhagyarajuakepogu]

Thanks, brother. It was worth watching for revising!

[@alexkerimate]

being an Indian American kid writing jee i never understood hindi teachers so thankyou so much

[@JH-ux1re]

Thank you very much! Cleared up my confusion! Gonna have my exam this afternoon.

[@QuangNguyen-vg1hr]

The video is very helpful and easy to understand. Keep up your great work! Thank you so much!

[@gamesx8528]

Very clear. Thank You!

[@Sammy-hl9wb]

Why is your equation for B different for each example?

[@NokulungaMacu-uq8qu]

You are a darling 😊, thank you sir

[@aloevera1269]

Thank you so much

[@ahmednagi7074]

conclusion the self inductance depend on the geometry of coil?

[@edgar4887]

Yes

[@Lecommandant_camroun]

exactly Jesus loves you! repent, God bless

[@gooddeedsleadto7499]

I understand it is because of some law or principle, but why voltage and current decrease when current increases, and the opposite when the current decreases? Underlying reason? Thsnks

[@edgar4887]

Faraday law

[@Lecommandant_camroun]

Faraday's law, and inductors are like that because inductance is the tendency of a circuit to store electrical energy in a magnetic field Jesus loves you!repent, God bless

[@balajothiadithya3144]

thanks mate you really are awesome

[@jjdh911dexter7]

is the R in the toroidal solenoid the inner, outer, or mean radius?

[@studyroa9045]

radius

[@aryannaik435]

Mean radius

[@jesussaenz2497]

@@studyroa9045 lol

[@fiyorbahr9346]

Check your calculator friends ,he is genius teacher. JG keep up

[@Ray-tf2ps]

How do i find the length of the self inductance

[@jakefromstatefarm7419]

Length would be i/NI(b)

[@muselimulaima]

I have a question I still can't understand. Anyone to help will be helpful. An iron of cross sectional area 800mm2 and of mean radius 170mm has two windings connected in series, one of 500 turns and the other one of 700 turns. If the relative permeability of an iron is 1200, find self-inductance of each coil and the mutual inductance , assuming that there is no leakage

[@kenennaaaa]

how did you get the value for mu 0

[@n3m055]

its always just 4pi*10^-7

[@islamicstatus5991]

Thanku so much

[@BIGRIP87]

how to find inductance of EI core?

[@kabandajamir9844]

Help us rc and lc circuit

[@ultifix2251]

Thanks!

[@PetakyahBuckley-ht5iz]

What calculator are you using because mine is giving me different answers? Can you solve the problems without the calculator? It seems pointless to use one. What’s the chance you’ll always have a scientific calculator in all situations? This stuff should be practiced by writing.

[@AmaanM01]

Ik it’s been 10 months but you might be in radians switch to degree

[@Lawlite-t2b]

Thx​@@AmaanM01

[@nur-ks2hp]

how you calculate L cause i get syntax error help me please

[@Lecommandant_camroun]

L (Inductance, in Henries) = [N(number of turns, unitless)*ΦB(Magnetic Flux, in Webers)]/I(Electric Current, in Amperes) hope it helps! Jesus loves you! Repent, God bless

[@yungheehong1775]

First problem: isn't "L" supposed to be positive not negative?

[@bryanencalada9574]

That is induced voltage not inductance, and the question is asking for the magnitude so its the absolute value

[@ahmednagi7074]

thanx keep it up

[@hhersssc2899]

When the current changes rapidly 2 A \ s, in the solenoid, due to self-induction the voltage of 0.04V is induced. Can someone do this for me pls. I dont know how to and i tried.

[@Uygʻun-q2c]

thanks sir

[@Lecommandant_camroun]

This helps 10^100000000 times more then most other tutors Thanks! Jesus loves you, repent God bless! And forgive us our debts, as we also have forgiven our debtors. Matthew 6:12

[@awadewa49]

You the man!!!

[@lilsamer3621]

there is some one who can tell me the formula of current in self inductance

[@laxmipathak4083]

Thank.

I hate plugging numbers into formulas. Lol

why aren't you verified? XD
