9:35 sir made an awesome beat while making cross

I am haapy to see a small lecture like who also feels 😂😂😂😂

Old lecture is best instead of new course😁

Magnetic field ki direction- Khachaak!!👍 Your way of teaching is superb sir

Watching this lecture exactly after 5 yrs!😮

Kis kis ka dream hai to meet at least one time to alakh sir

When i observe your teaching, a burning desire of studying physics arises in my mind !!

thanks for ur help and we will do our best and make u proud

I think sir ne psychology bhi padhi h, how he reads our mind , sir you always surprised me .😃

Super 30- ANAND KUMAR SIR SUPER 1.3 MILLION PHYSICS WALLAH SIR 🙏🙏🙏🙏

9:34 musical beats❤❤(2x)speed

5 baje video upload!! Itni mehnat❤️ hats off to you sir👏👏👏

Normal People: "11 mins!!! It's such a long video!!" PW students: "Haha!! Aaj toh chota sa 27 min ka lecture hai 😎"

╔══╗╔╗ ╚╗╔╝║║╔═╦╦╦╔╗ ╔╝╚╗║╚╣║║║║╔╣ ╚══╝╚═╩═╩═╩═╝ this channel...!!!

At 2× speed, 9: 35,,sir is good musician too

Sir aap Apne t-shirt ka question solve kare please. 😜

Ohhhh my goddddd.... he's a saviour..I was wasting so much time reading the book

Subha Subha apki video dekhna MATLAB Aaj din acha jayega ☺️

I don't know how, I am shocked how you can understand the exact question that i haven't understood and start re explaining that again, it seems like you have mentally connected with me

*ONLINE NOTES* 📄📌 Field at the interior of a toroid 22:09

Dear Teacher, Thank You For Continually Inspires me to do my best You help me strive for goals, I found guidance, friendship, discipline and love, everything, in one person. And that person is you Happy Teacher’s Day!!

Alain Pandey =one of the best teacher around world for students who want to clear their concepts completely

Sir 10:38 pe ye reason bhi to ho sakta h ki outside the solenoid magnetic field is zero.

It just imaginery platform ,which have been taking New vision in our career pt ,that has large million of candidates watching this lecture vedio. Sir you are be great supervision in future Time that's you are destiny or adversity children especially these all children to be great goal to be achieve . Thanks so much

May god shower all the happiness on you and your family. Thank you sir for this amazing lecture

Sir ki video pr #advertisement# pura dekho sb log.... jisse sir ko jada se jada rupee mile...its free help to sir... please do it😊😊 Apne sir best h 📺📺📺📺📺📺📺 RU-vid tbhi pay krta h jb advertisement pura dekhte h Hm sb sir ke lia itta toh kr hi skte h jisse sir ko bhi kuch thoda jada mil jayega...pr apna kuch nhi jayega

Sir your t-shirts are very amazing 👌

All students dream is to being engineer, piolet, doctor........etc. But my first dream is to meet Allakh Panday sir. Whose dream is like my.

Aaj kal physics wallah me itne achhe achhe physics ke teachers hai but phir bhi... pta nhi q..?? Mjhe lgta hai Alakh sir se achha koi nhi smjhata.... inke ye wale videos pr 2 year se koi bhi comment nhi krta it means koi nhi dekhta ... But main inke yhi 2-3 saal purane videos dekhti hu ...😊😊😊😊 q ki mjhe inke purane videos hi achhe lagte hai aur wo bhi ALAKH PANDEY SIR ke..👍👍👍👍✌✌🤥🤥✌✌✌✌✌✌🤩🤩🤩

The amount of current is going to inside of amp.loop (Q)is equal to the amount of current going to outside, so net I =0

8:45 sir because we are using solenoid and in previous video we assume that(B) outside the solenoid is zero 0

*WHO UNDERSTAND THE TEXT* *WRITTEN IN SIR'S T SHIRT ?* *LIKE LET ME KNOW PHYSICS* *WALLAH ARMY*

Dear You tube Make 3X speed

Thank You Sir for such videos

The toroid becomes a mini arc reactor l think it was the inspiration for Tony stark while he was studying with alakh sir at 13:28

East or west physics wallah is the best 🤟🤗🤟

13:57 best tune

Sir i git 98 marks in chem and 88 in phy all credit goes to you sir thank you and love u from jharkhand

I literally took 20-21 12th class as joke.. Shit I'm dead

Love you see sir you are doing Hard work for students

13:54 listen it at 1.5x Awesome beats made by sir 😅

A very beautiful GOOD MORNING sir

Duniyas best teacher alakh Sir ritu mam and vishal tiwari

Plzz tell aap alkyne or aromatic karoge Ya phir seedhe hallide I love u sir

9:32 listen it at 1.5x Awesome beasts made by sir 😅

Sir I've just grown fond of your 'khachaak'. Thank you so much. Easy to understand.

Tu ta dudu du🕺🕺 awesome beats..14:25 😂😂

You are extraordinary and very unique ,sir😊😉.

Listen the sound 9:40 when sir is making cross .... Seems like 🐎 🐎 🐎 Horse is running ...🤩🤩

Woww sir 5 bje video uploaded... Thank you so very much sir hmaara itna khyaal rakhne k liye😊😊

At 14:00 I literally feel the music rythm of marker

This video was very useful for me...I understand everything...clearly...😇...

Sir jasa koi nhi pdha sakta I enjoy learning with his white board instead of smart board . Sir physics mein expert hai.❤Gr8 person👍✨

Thank you sir❤❤

One word me Kahu to DHAMAKEDAR class 👍👍👍👍👍👍👍👍👍

You're just brilliant sir... Bless your knowledge lots of love sir🙏🙏🙏🙏

Sir toroid lecture k notes aapke website pr nahi h. Plz see to it sir. I'm following you since class 10. U r avery great teacher. And also the best motivator. Thank you sir.

sir your teaching style is awesome 😍😍

9:33 - 9:45 listening that music with different playback speed for infinite time

We: what is the direction of magnetic field...???? alakh sir: khachak khachak khachak khachak

13:34 Magnetic field inside the solenoid

Me in exam hall:- aeee khackk aeee khackk😂

8:40 2 loop me current opposite direction mei jakr magnetic field cancel kra denge shayad ....

Sir aap bhut achha explanation karte ho 🙏🙏 THANKS SIR ❤❤

If a closed line integral of magnetic field becomes zero that doesn't imply that magnetic field itself is zero. In our toroid case, magnetic field is perpendicular to the surface i.e. pointing outside and inside the board for the Ampere's loop. Magnetic field does exist outside and inside

Who else was able to feel the beats when sir was drawing cross inside circle🤘🤘🤟🤟

Iinside=0 in outside coz the point q is outside the toroid then no current will pass through it.. 🙌

Sach batana kis kis ka ye lec dekh ke face mai smile aya 😅😂 chota lec!!

8:40-i inside is 0 now also because magnetic field outside solenoid is nearly zero.

10:00 better way to find B on point Q is to draw the amperes loop on right side, as there will be no current inside thus B will be 0.

Current ki direction me thumb rakho aur fingers ko curle kro - "aae khachak, aae khachak" 17:40

My jee is over but still not able to resist from watching your videos.... An addiction which is helpful 😍XD

I will be appearing for jee next year. I don't know why but I feel really sad that by next year I won't be watching these kind of lectures anymore (I don't plan on taking a drop incase I don't crack IIT). I've been watching alakh sir, unacademy's namo sir's class 11th, 12th lectures since class 8😂😂. Although I didn't understand shit back then I still watched the videos. It just felt really nice

Sir just because u I don't need to take coaching classes. Who other like me is doing so please leave a like

Bhaiya, syllabus peechai hone lga, aap please jldi jldi videos bnaiye jisse syllabus jldi complete hojaye, thank you.

8:39 jitna current andar ja raha hai loop ke utna hi bahar bhi aa raha hai isliye net current zero hai.

Sir ap to bhagawan ho ap ka jasa physics ko i nahi para sakta ha. Pura india ma nahi ha apka jaisa teacher.🥰🥰🥰💓💓

8:40 as per in last lecture as the the direction of the magnetic field a one ring will get opposes by the magnetic field field of the adjacent ring to it that's why the B(outside) is zero

Sir u are great , I love all your old lectures only , they are great

9:32 2x pe dekho aisa lagega ghoda daud raha hai😂

Thank you sir😊 Love frm orissa❤😊

Current inside is zero because of circular infrastructure and for the neutralization

thank you sir for this wonderful lecture🥰🥰🥰❤️❤️❤️

Watching PW sir's old lectures in 1.5X is quite helpful if you have less time to cover your syllabus

Outside the point Q ,the current is zero because current comming out of the plane is cancelled e exactly by the current going to it.

Maturity realises when you know that - agar nhi padhenge toh hamara hi nuksaan hoga😢

*Sir GOC ka notes kb upload kriaga*

sir kyonki net current aavanti=net current jaavanti

Respectively sir the reason is ....the net current is zero inside the ampere's loop assumed at point'Q' outside the toroide because 'i' current is come inside it and then go outside too 😃😃 sir u are very amazing teacher and also too surprising❤❤

8:50, sir the current coming in the toroid= current going out the toroid. thus i inside= 0

Happy Teacher's Day Sir 🙏

Sir lovin d lecs....d work u have been doin is commendable...have been following ur hand notes assignments too...love dem❤❤

Your free hand diagram is also awesome 💞💞💞💞

Derivations become so easy when u teached 👍👍

Because B vanishes outside the toroid i. e. why point A has B =0.......in 8:27(maybe)?

It was very helpful Sir . Thnks a lott✌️🙏

9:11 If there are odd no. Of turns

This is best handmade toroid structure i have seen Sir apki drawing best hai😁🤩

Watch from 9:31 in 2X...... Tat tad tat tad tat tad......... Sahi mein maza aa gaya sir
