- A moving coil galvanometer works on the principle that a current-carrying coil placed in a magnetic field, experiences a torque. The coil springs along with the radial field ensure the deflection to be proportional to the strength of the current.

One of the most underrated study videos , loved it
True man!
so true.....
Crct
I'm a teacher and I'm spell bound by how it appears done so easily.... while its not actually a easy one . You use so sophisticated tools to depict . Extraordinary brother
You are not a good teacher, don't give excuse
@@dextro9322 😂
I hate school
True, that too an explanation so clear and vivid. Thankyou!
If engineering was taught like this we would have got engineers rather than graduates....Amazing explanation of understanding the problem and finding the solution...Keep going...❤️❤️
I only just watch this with rough knowledge about magnetic fields but damn, i could watch you a day and become an engineer tomorrow
I never comment on videos but with this type of expertise in explaining the concept i just couldn't help my self .
Thank you sir.🙏🙏
Firstly at 2:00 min I am able to understand what I was actually searching......
Secondly calm voice.......
Thirdly much patience..........
Fourthly I am able to NEET/JEE pyqs without taking any help from Edtech channels.......
Fifthly Very very Thankful to you ❤
2nd time i found u in comment section🫂
@@navyblueskiess ooh really.... App kya karte ho ... Student ho konsi class mein padte ho neet ya jee kar rahe ho batao....
Most underrated channel in existence
Happy Teachers day to you @Mahesh Shehnoy sir. You are the best teacher for me. Keep educating entertaining us with physics and your awesome soothing voice.
Soothing?
@@comic4relief everyone has difference experience but get the same knowledge:)
Absolute content.
He arises with a ton of questions.
His whole lecture is about answering the questions.
Yess ofcourse
I had to make sure I say this
U r a wonderful teacher ..
Wow what a clear explanation!
thanks from 🇪🇬
I srsly don't know y many ppl don't watch these kind of things...
This is so well understood with lot of 3D effect 👏🏻👌🏻❤
I never usually post any comments, but I'm bound to do so for this video!
Mahesh sir, You have completely changed my perception about physics 😢
No one could have explained such a complicated device so efficiently.. hats off to you 👏👏👏👏👏
The physics teacher of my school and coaching just care about theoretical and question-solving aspects even for machines/devices like moving coil galvanometer, transformers, etc., but i finally understand the true essence of principle, construction, working and associated formulae..
Thank you so much from the bottom of my heart 🙏🙏🙏
I would be highly grateful and would love it if you could arrange the videos chapterwise in sequence of the topics.(especially class 12 physics)🙏🏻🙏🏻🙏🏻. Cause I find it really hard to find topics on this channel 😔🙏🏻🙏🏻
Btw I love ur channel ❤❤. Your explanation is superb. Never seen a teacher like u ❤
Others create lectures while Sir you create master pieces !
Ultimate Interesting way of teaching . Really enjoyed a lot even than the usual hobbies ... Thank you !
Best Expanation Ever ...... Salute Youuu
Love from Nepal❤❤
Isn't this is the way that we all should be taught😊...... you made my day❤
The high education material is explained as if it were child's play. That's the talent of yours, sir Mahesh Shenoy
phew! finally understood the working of a moving coil galvanometer. Thank you so much for the awesome explanation!
I couldn't... The magnetic field isn't even going through the coil...
@@yashmal1k No... That's not how it works...
We pass currently through the coil and hence the coil starts acting as a magnet... And this coil is placed in between two poles of a different magnet... So it turns (since unlike poles attract)...
THAT'S AN AMAZING EXPLANATION!!! YOU'RE BORN TO TEACH KEEP GOINGG
Just flawless explanation with student frndly approach..
Fabulous Mr.Mahesh. No one on earth explained the galvanometer so precisely and technically. Poor galvanometer got special respect because of this video or otherwise who cares for it❤
Absolutely mesmerized. Thank you so very much for these lectures. No other source provided as much clarity as this.
No one ever told me and my classmate why radial field.
You explained it very well
Thank u so much. Finally understood the concept restoring torque of the spring and why radial field is necessary. Best video on galvanometer on youtube.
Yessssss
Brilliantly explained radial field!! Kudos sir
Even he deserves respect as much as we respect PW😊
very best no words to explain physics is now more interested to me after having teachers like you
A lot of thanks about every simplifications you produce khan
india is a country of geniuses
Thank you very very much. I saw many videos, but only this one made me understand the concept perfectly.
All respect from Egypt 🇪🇬❤
Fantastic and so simple 🤗😍
May Allah bless you 🌸🌸💞
Amazing lecture. Extraordinary teacher. I have today understood this topic in 2 years. Really appreciate your efforts. 🥳🥳🥳
This video cleared all my concepts and helped me completely understand he working and modifications made to a Galvanometer. A very big hearted Thank You!
Omg things like this make me realise just how ingenious we humans can be!
Perfect explanation. Thanks
Clear as crystal! This video is spot on! I understood every minute detail, and sir you gave me an added interest in physics!!!
Thank you sir concept very clear i love to study by seeing the diagrams and vidoes you explained it very well my doubts are all clear
தலைவா நீ வேர ரகம்
Your videos are really easy to understand
Thank you so much Sir
This was a great video! Now I know what the heck a galvanometer is, and it no longer feels like a black box!
Very nicely explained , Thank You
how much i learned about galvanometer in first 4 min of this video i didnt understood that much even in 40 min in my school..why can't all the teachers be like you..
God level teaching mannn🙇♀️💗 hats off to the greatest physics teacher ❤️
My god! Breaking such a twisting concept into easy to understand chunks. You guys are awesome!
thanks khan academy... i was not able to understand why B always perp. to M due to design
Thankyou so much Sir. You nailed it!😍
BEAUTIFULLY EXPLAINED AS A STUDENT CANT THANK U ENOUGH
Amazing!!!! 💫
I like the way you explain things....👍
Omg... I can't get enough of intuition.. wow.. mind blowing 🥳explanation..
I saw many but this is last one and finally i understanding
BEST EXPLANATION!
Make video in hindi . So it help more .if u are an 🇮🇳 Indian
kya feeel di hai guru kasam se maza aa gya❤❤
How beautifully You have explained the things ..... well done bro.... 👏
The Best explained video i have ever seen..thank you sir
I'm recognizing you voice ( floatheadphysics)...😘
Love all your videos, and this one too thank you sir
the accent does it for me (love the accent!)
Khan academy is definitely a lifesaver :)
How amazing👍👍👍👍
Happy teachers day sir
You are a great great great teacher thank you so much this is my 3rd video on the same topic and I really think I do understand much much better now thank you again
Thanks a lot sir!!!
Best animation great explanation 💐💐
Amazingly illustrated… 💯👍👍
Legitimately a fan of yours from now on sir .. thanku for clearing the douts so efficiently.
AWESOME EXPLANATION!!!
Very great theach this sir thanks a lot 💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖
Omg I am totally speechless how beautifully he explained it amazing
Really thank you sir... Best explanation....
Damn, everywhere i go they just teach that there’s a spring a cylinder core and this this thing but nobody told me why is it so , really helpful vid , now i guess I’ll never forget how it works ❤
Thanks of lot❤❤❤ great understanding.❤❤
in ncert how the angle was constant wasnt clarified properly, thanks for explaning
All your lectures are gold!Thank you sir❤
Wow what an explaination
Much appreciated.. but didn't get the last part.. you've make the other field lines invisible except the one acting in parallel to the coil.. But what about the other field lines, aren't those making an angle with the coil when it turns? If not, why and how?
this man deserves oscar]
If the coil is always aligned with the magnetic field lines how does the coil turn?
U made it super easy to understand..
🙌🙌🙌
You are a good teacher
Wow! This along with the equation of a wave also from Khan Academy is the best video I have ever seen.
Thanks very much.
12:25 was confused about that but now it's clear👍
Loved it... Amazing video
Amazing explaination 😊🤗 thank u sir❤️
U r a great teacher
Beautiful!
underrated loved it .
bro wow this is so good
🤩🤩🤩🤩🤩🤩🤩🤩🤩
Thank you so much I really appreciate your help to let me really understand it in this simple way you really helped me and I'm so thankful for you ☺️
Sir, why would the field line touching (in line with) the coil only produce a torque on it? why not the other radial field lines; they are also at some angle to the coil, right? pleaseee reply, id be so grateful.
btw, I love your videos, you are the only person who I turn to when it comes to really understanding physics. please keep doing what you do. just wanted to let you know that all of us are grateful to you.
Thank you!!!!
this Channel is soooo underrated
literally the best explanation one can give💗
For the1st time i understood this👌🏻🔥👏🏻👏🏻
Tqsm sir🙏🏻♥♥❤❤
Angle between field and pointer
Really excellent 🖤💝
Thank you so much
Thanks a lot. you are great.
