this video deserves more than 100k thumbs up.

Paused the video to thank 🙇. Gratitude was overflowing .

You had me at "...It feels good to say that... go ahead say it..."

you are awesome And I love ur voice too

When I am bored while studying I watch your videos ☺️☺️

Bro, your videos are straight fire. this one and the one on cyclotrons are all anyone could ask for when being taught concepts. Thank you for teaching this and taking the time to explain concepts and big picture.

thank you khan academy....you have helped me a lot

thank you indian surrogate teacher for saving me again from my american classroom jai hind

Whooo......This guy is unbelievable 😮😮😮😮😮😮

For those who guys wanna know why everything are not magnetic: 1. The electrons occupying the orbital must me single (else they would cancel each other out) 2. Most objects we see are made up of many domains which may or may not consist of similar atoms which have dipoles. So the domains may cancel each other out unless they are also aligned. 3. The atoms in the domains must be aligned properly

everyone gave the quantative definition of magnetic dipoles but u made me feel the concept. thanks a lot

This is some phenomenal teaching.

Love the u go through the concepts and get every detail

Awesome lectures and lecturers 👌

YOU ARE A GODSEND! Thank you

Wow. There is a lot packed into this video, and you present the information in a very understandable manner. Great job.

Wow. The only good video I found on this topic. And it is a REALLY good one!

Brilliant explainer. I'm pretty new to magnetism (for a project) and this helped out a lot. Thank you

What fantastic , marvellous, full of knowledge video... I'm running out of words love the way of your teaching and make us think differently ❤️❤️❤️❤️❤️❤️

Beautifully explained

sir plz plz plz make video on how that expression of magnetic dipole moment came

Thank you so much sir..

wow! thanks! love your videos!

My friend! Thank you so much!!!

Excellent!

Love your explanation

Perfect explanation 👌😉

Great explanation 👍👍👍

Awesome lecture really...all doubt cleared...

Well explained...

fantastic video!

sir your passion for physics envigours mine everytime I watch one of your video! THANK YOU FOR YOU EXPERTISE!

great, thanks

very nicely explaind sir, thanks a lot.

Excellent graphics!

Killed it😎

Excellent Video.

Superb explanation .

Thanks amazing

Amazing👍👍

thanks a lot it helped me to understand to concept very well

Nice explanation

Thanks a lot

Thankyou so much sir🙏😇

Excellent 😮😀👍👍

Thank you!!!

U r awesome 😃

please do more videos on Lenz's and faraday's laws🙏😇

THANK YOU SO MUCH

Super good

i really like when you say 'magnetic dipole' instead of 'tiny magnet', you are greater than 6G thumbs up

Super💯

Best ❤️

Why cant my professors be like you......

best video

Good video

Great video!! ...I did expect the UNITS, also, of the ELECTRIC dipole moment (or an explanation)...left things a little incomplete. THANKS MUCH!!!

This is concept and this is real physics where it is not a strain on the mind rather simple things as a 10 year old can learn , what to explain , in physical tems what the formula is try to speak and make it visualise us ,we no long need to remember every formula is boom we can just tell the formula right . Thx man , one suggestion just elaborate more on the formula like how A incr. The B as it more no. Of mag. Field line can pass through it , more current , more B , more turns more N ,little bit more elaborate and basic is better than any Netflix show and simpler.

great :3

see for example KZfaq Stern-Gerlach Experiment U2 07 03.

can you pls make a video of its derivation which you said you'll do it in a future video ?

If a current loop had a varying thickness of a circular wire (cross section is a circle through out the wire), would the area component for the magnetic dipole moment still be the same as a current loop with a non-varying thickness circular wire?

If you assume the Exchange Interaction is responsible for the magnetic field around a 'current-carrying' wire (the Exchange Interaction aligns electron spins to prevent a Coulomb force build-up between electrons pulled together by the charge separation (battery or power supply) attached to the 'current-carrying' wire) Nature always seeks a lowest-energy condition, a move towards a lowest-energy equilibrium. Since aligned electron spins increases distance between the electrons, the Exchange Interaction is enabling a reduction in the Coulomb force that the bunching-up of electrons in the wire can lead to. Alignment of electron spins does 3 things: 1) the 'like' magnetic poles of adjacent electrons are now aligned parallel - 'like' poles repel; electrons keep a distance from one another due to this 2) aligned electron spins was identified in the 1920s as the source for magnetic fields 3) so a magnetic field around the wire appears due to the aligned electron spins 'Drift velocity' - the astonishingly slow and random motion of conduction-band electrons - could not produce a coherent magnetic field (consistently polarized in the same direction as is the magnetic field around a wire). 'Drift velocity' puts the lie to what we were taught in college, that 'electric current is electron flow in the wire' .

Why does the magnitude of the magnetic field not appear in this formular for magnetic moment.

The reason I think everything is not magnetic is because not every molecule has free unpaired electrons that spins around and creates a magnetic field. Thank you I understood well from this great video

Floathead physics?!

This guy should adopt my physics professor and teach him how to teach

Hello boss am from Pakistan Have u uploaded any video about Hall effect??? If yes then share it plz

Hey i got a doubt....as magnetic fields are formed due to dipoles and if we see in an atom level then electron spins in its own path making a current loop, okayyy but how do u say electrons act as a dipole....where is the current loop and how do we consider electron as a dipole(as electron is a monopole)

❤❤❤

Nothing to explain him except a single word "satisfied"

I think You should Join Physics Wallah. What a Amazing way of teaching!You deserve more views

tqqqq

ive been beating around the bush with magnetism all day, needless to say this helped

Sir we also define magentic dipole moment as pole strength*distance between them which is similar to electric dipole

When will you upload next video

Very nice presentation: I was wondering what is in a magnetic line? how do the magnetic line form? from what?

1st comment

Hello Sir B.tech aerospace engineering in Cambridge university total fees please speak in youtube

awlawww❤

I am being effected by waves through walls in unit home from technology being used what to do

Sir please make lectures in hindi on khan academy India YT channel.

This voice is of Ashish Ranjan Sir, an Ex-ISRO scientist

I'm confused because I've heard of the magnetic field strength being referred to as B... and I know that m must not be the same because its formula is different, but its also referred to in this video as the tiny magnets "strength". How is this strength(m) different than the magnetic field strength(B)? Any clarifications would be greatly appreciated, and would help me a lot in getting to learn the subject.

Why area matters in magnetic moment

Physicists are hopelessly confusing about 2D, 3D. Please explicitly state or picture whether the phenomena is 2D or 3D. Atoms are 3D but often pictured and portrayed 2D. Don't know in this lecture.

How can a electron starts revolving ...without putting battery ....

You said that electrons move from south to north pole ,indicating direction and u said forget about it just now.Buttt my mind doesn't hear ur words!!!!!!!!!🤯

Can you reply...plzzz

Who else is a fan of Mahesh Shenoy ?🙋

*_Summary Of The Video :-_* *Magnetic Dipole & Dipole Moment* * Current loop behave like a tiny bar magnet no matter what the shape of loop is. * Technically we use a term for tiny bar magnet known as *Magnetic Dipole* * The strength of the dipole is determined by the term *Magnetic Dipole Moment* * Magnetic Dipole Moment is a vector quantity * We can determine the direction of magnetic moment using our *Right Hand Rule* * If we clasp our right hand in such a way that our four finger represent direction of current then our thumb will showing the direction of magnetic moment.

Faking accent😒

bring Sal Khan back, this guy's voice is the worst
