- Let's learn what solenoids are, and why are they important. We will see that when we pass current through a solenoid, it produces a magnetic field similar to a bar magnet.

Brilliant video! Really clearly and well explained. This is the 12th video I've watched on TH-cam on selenoids and this the most enjoyable one for me. I also actually feel I understand solenoids a lot better now. Keep up your great work! You are an amazing teacher; one of the best. It's not just the way you explain things but you also have such an engaging voice, that I want to listen too.
I fell asleep when I watched the last TH-cam video on solenoids. With your unique voice and they way you explain things, I think you could make the most boring subjects super fun!
2:00 ooo
2:58 heyyy
3:48 tadaa
it's literally the most simplest and efficient explanation of explaining a topic. love the channel and the quality of video explanations. thank you so much for your efforts sir
your such a good teacher
3 of your videos made me understand better than 10 lessons with my teacher
You literally made me want to become an engineer
Amazing video sir you don't know how you have helped me by this video I could not get this from the starting of the term but now I got it this will really help me for my board exams this year
I have a piece of advice that if you guys spread the message by advertisements that Khan Academy is teaching Indian syllabus too this will lead to rise in subscribers
I just don't know how I can inherit this technique of explaining things. It is just like a super fun.
Ikr, I always wanted to be a teacher, and these videos are teaching me how to teach, along with physics 😆
I have understood it still better thanks for explaining 😊😊
Amazing! I understood each n every thing ...so clear
THANK YOU
So interesting 😄😄😄
Thanks :)
Thank you !!!
what did we learn in the video?
that im dumb
thanks sir
Which factor will have greater impact in changing magnetic field N or I ?
Depends on a lot of things. By what magnitude I is changed, what how many coils are increased, diameter of the coil, conductivity of the wire, etc.
thanks bro
2:00 ooo
7:03 soft as a pillow😂😂😂
THANK YOU SO MUCH!!!!!
Sir are solenoids electromagnets or the magnet formed by ppacing soft iron core electromagnets???
From what I could gather, every conductor which carries a charge and possesses a magnetic field due to it, is called an electromagnet.
When we introduce an iron core (soft or hard) the electromagnets become stronger.
This explains that the iron core which we use in a solenoid enhances the effect of that solenoid, or rather we call it the electromagnet, and itself becomes an electromagnet. In other words, the soft iron used becomes a current carrying conductor too, and hence possesses a magnetic field which adds on to that that of the electromagnetic solenoid.
6:40 no sound
Really digging the enthusiasm, and love those drawings, really well made
i guess im asking the wrong place but does anyone know a tool to log back into an Instagram account?
I somehow lost my account password. I love any tricks you can give me
@Milan Zeke instablaster :)
@Yahir Noah I really appreciate your reply. I found the site on google and I'm in the hacking process now.
Takes quite some time so I will get back to you later with my results.
@Yahir Noah it worked and I finally got access to my account again. I am so happy!
Thank you so much you saved my ass!
@Milan Zeke Happy to help :D
Great Video! Thank you! Just one thing: Solenoid doesn't come from German, it comes from Greek. In German pipe means "Rohr" and shape means "Form".
I wish my teachers taught like this😅
i am sure that noone would have thought to arrive at a solenoid as you did sir, hatsoff and thankyou sir
This was really nicely explained bruv. Good job.
And of course thanks!
is everyone thinking of what i am thinking. a solenoid engine for space and
ya heard it here first solenoid space engine. i just need a vacuum chamber tunnel, a coil , some dust or gas , energy source and some camera. to start testing
This is as clear that even my teachers cant
1:59 hahah

copied 1st line
Soo masically if its one circular coil the magnetic field will have circular magnectic field but when more than one flat circular coil joins(solenoid) it forms an oval magnetic field
On what does the strength of the magnetic field depend, the diameter of the wire, for example, the diameter of the iron pole, or the strength of the current?????
Thank you so much i Iove you
1:57, lol
OooOoohhhhHhHhh
Is the magnetic field varies with the size of iron rod inserted in core
thankyousomuch sir!
Thankyou teacher
This was a life saver. Thanks a lot!
Thank you man, I appreciate this
5yr old video but still helps a lot ❤
YOU EXPLAIN THINGS SO WELL, IT MAKES ME ENJOY PHY
This is the best physics video I have ever seen. You have explained the concepts so well, and the pictures really make me understand it much better. Thanks a lot sir🙏🙏
I'm a little confused by this visual. If you've studied magnetostatics you know that the magnetic field outside the solenoid is (at least very close) to zero, yet it's drawn in here. Is the idea that as you increase the length of the solenoid and decrease the distance between the coils (like an ideal solenoid) that the net magnetic field outside the solenoid get's pushed so far away that it might as well be zero?
Yes, you are right. Even in a regular solenoid, the magnetic field inside could be few orders of magnitude higher than the outside. So assuming field to be zero outside is a good approximation!
I hope I get a teacher like you in college 🙏🏻✨
Thanks for this video!
thank you as always
Dudeeeeee this 8 min video is life saving.... Thank you so so so much and woo i finally got it ❤
Ur videos r amazing
I am going crazy like anything
Really appreciateable
Also it's my 1st comment ,🤪🤪
Thank you sir
Thank u so much sir! Understood very well by watching ur video! Keep rocking!:)
Where is the magnetic field strength strongest in a solenoid, inside it or at the poles?
Where is the the hindi version of the same lecture ? Some time ago it was available.
Great and Outstanding!
Obsessed with the vids.❤
you cvan do this in a 33333 coloor crt beam control circuit for closed loop experiments?
Sir , where is the magnetic strength more , near the poles of solenoid or inside the solenoid??
! Oh that was!
I don't know y some people disliked this vedio is so amazing vedio ever on solinoid in youtube...just amazing... I respect your work.
I think of the coil of wire as an inductor! Awesome vid.
just amazing thank you so so ............................... much
amazinnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn!!!!!!
Is the magnetic field independent of length and area of cross section?
Yes
@@arunikaraghuvanshi3412 thankyou
How tho I didn't get it
Sir I can't explain in words what yu deserve in return of your lecture ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
so clear and helpful!!!
Amused!
Literally first time got that
A man with no haters ❤❤❤❤
Thank you very much , this is really helpful
AMAZING!!!!!!!!!!! Thank you :)
An Excellent Video!!!!!
whats the yellow line going straight into coil of wire? Where is that field line coming from? Is it a magnet?
the lines resembles magnetic field resulting from the passage of electricity through the wire
@@VENUS-uc4yy Yh ik that bozo. I’m asking about the one straight line in the coils of wire. Where is it coming from because magnetic field of current carrying conductor is in concentric cirlces
Good videos 👍
Thank you!
Thanx Sir !!!!!
Helpfull video
thanks sir
thank you
ooooooooooooo
Love these vids!
Amazing explanation
THANK U
Excellent sir ☺️
The one who disliked can't understand it this concept by any one in this world
awesome
You are brilliant sir
THANK YOU VERY MUCH!!!!!!!!!!!!!!!!!!!!!! 😄
Sir... Is that you in the Hindi version...? ....But the voice varies...
In some videos he is and in other there Ram Prakash Sir
How can magnetic field lines merge with each other??
The north and south field lines do merge as you see in the field diagram. If you place two magnets facing each other one with N and the other with S, The lines will merge and that is what is happening here.
Beautifully explained !
What is meant by demagnetism sir??
When you place materials that are attracted to a magnet in a magnetic field for some time (depending on the material), They will magnetize and after some time(depending on the material as well), they will demagnetize.
Thanks.
you should include formulae
I would like to bring up the full story to solenoids, which has been omitted here, that the net magnetic fields outside it is always zero, while it only exists inside. This can be proved by using alternate, clasp right-hand rule.
