Awsome explanation with the wonderful voice..
Right
Ya
Hmm
i like the confidence in your voice..that make me focus much more on the topic.
U are right bro 👊👊👍👌
MUSTT READD!!!!!!!!
To be VERY VERY HONEST WID UH SIR....
I don't attend my physics class at scul many a times and put up a holiday from scul for my SELF STUDY at home and it's JUST bcaz of uhhhhh
.......
I listen to ur lectures and that they are just sooooooooooo much of understanding and THE BEST..
All my teachers refuse to explain me the concepts bcaz am a bit of person that cannot grab concepts easily....it takes a lot of tym for me to understand things..that why everyone and all my classmates call me pea brained or THICK HEADED...
But fortunately I got a teacher like uhhhhhhh....THANKEWWWW SOO VERY MUCH.
Anyone who liked it do hit like
Don't worry, just study hard and do hardwork then no one will call you pea brained.
Hey bro it's only cuz of ours edu. System...Same here. I m also that of stu who can't grab physics easily. I ask my teachers to plz solve my doubts but they🙄😑 ...But the really this channel is awesome......I m getting a bit interest in physics after watching sir videos.....IDK why he is too good ..
Just study and revise everyday write your short notes in a diary and revise it daily you will be like me in board 2020 I got 97% Mark's so study hard
Your English is OP
I think you are the one who wishes to understand these concepts deeply and that's why you take time and not because you are a slow learner
BTW i also have the same kind of attitude😀
Fabulous lecture...... This is one of the best lectures I have ever heard in my life.... And my concepts are cent% cleared now..... Thanks to you for such brilliant uploads....
Yes bro Right
It's still useful for 2022...
Yes man
this channel provides real knowledge no drama no business, so glad to have something like khan academy
You are great sir anyone agree give like
I agree🙋♀
Agreed
Like bdane ke liye bola hai na tune bhen😁🙄
Veekh mangne ka bhi ek tarika hota hai
Really blessed to find such a brillant channel on youtube .
I love your teaching way, Thank you sooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo much
Physics should be taught like this rather then recalling the slides on the screen...
because we can read theory in different books what we need is this, the practical approach of understanding the topic
damn!!! i mean just WOW!! I STARTED magnetism yesterday and i was like yeah ill do this chapter its pretty easy! now it's day 2 and its been 1 hour since im praticing these, god!! i was actually searching for some visuals and thank god i found your channel, im so impressed by the fact that you actually MADE IT EASIER FOR ME!! thanku sooo much*100000!! love you khan academy

Bass yeh video k liye sir Pranam apko 🙏🙏🙏 4 saal se electrical pad raha hu. Bohut video bohut sir dekhlie. Par aise 1st dekha. Hat's off to your effort for us, amazing thinking. I hope it will help many like me who are very weak in science & have a fear for this type of concept.
Awesome explaination! God will definitely bless you.
His aah...!! and ohh...!! make a big smile on my face 😁 and I listened it twice 😂....
Ram sir you are just just awesome!! 😊
Sir which software use make wonderful tutorial
Thank you
Useful for term 2022
This is the best explanation for a solenoid and can be used to understand:
(i)why solenoid is needed?
(ii)what actually happen when a single ring is added?
(iii)why a large number of rings needed to be added?
(iv)finally, why is the solenoid made the way it is?
(v)what the hell is electromagnet?
(vi)advantages with solenoid rather than a bar magnet.
(vii)disadvantages.
(viii)its uses.
(ix)what is soft iron and how can it be used with a solenoid?
(x)why only soft iron and not the other iron is used in it?
BONUS-for teachers:(xi)how to do humour while teaching.
Bonus point was some seriously good
Between he teaches the best he is outside of this world literally he is amazing best
hello sir, i am also teacher, i got for the first time physics sub, your videos are very helpfull to explain the concept of physics.
I really loved the hash tag you used. It inspired me.
Same siso.....❤❤❤
Me too
Yeahhhh💕
Me too
It Just looking like a wow ❤wow wow wow 😊😊😊❤❤❤
Kuch aise 😁
U r the best sir
Your teaching skills can beat teachers of vedantu and unacademy
🎊🤩

Waah bhai kya samjate ho yaar
Likes for this person 👍👍
One of the brilliant teacher of physics
Which makes me easy to understand magnetic effect of current . Thanks you so much !! sir.....
Sir
I want chemistry class in Hindi
Very Nice explanation.... Awesome n Superb...Thanx n Pls keep it up..
You are best teacher of physics
Who thinks that it is the best channel for class10 CBSE physics
👎---left hand thumb rule(Oops🤣)
Chutiya vo left land hi hota h kamine
@Seldon Angmo no I don't think that physics wallah is best
Rkrajnish The real hero yes bro I also don’t think that physics wallah is the best
Wo sab sirf marks ke liye teach karte hai but ye knowledge ke liye
You are the best 👌👌👌👌👌👌👌👌👍👍👍👍👍👍👍👍👍👍

After the ah.. and oh ..
I was anticipating eee... when the field lines resembled a bar magnet🤣
But siriusly great job man
Love your teaching
Sir total physics aise hi experiment ker do please sir

U r the best ever
Best teacher I ever had🙂🙂
Excellent explanation...thank you...keep doing these kind of videos
Like your voice!!!!!#amazing explaination
Solenoid is a coil made of insulate copper wire
Solenoid acts as a bar magnet
Magnetic field can be controlled
Electromagnet is not a permanent magnet
Electromagnet is made by placing soft iron rod inside solenoid.
Way of teaching is very fantastic 👍
