Magnetic moment of electron around a proton | Moving charges & magnetism | Physics | Khan Academy

Let's explore what the magnetic moment of atoms depends on. We will see that the magnetic moment of atoms is directly proportional to their angular momentum.

what i learnt from this 15 min video > > > > what i learnt from a 2 hr long lecture..

[@NaN_000]

Same

_"hey common electron is wave"_

[@feelingzhakkaas]

one of the best ever lecture explaining this subject. Tooooo Good sir. you are blessed.

[@karuppiahmani8125]

May be protons have larger mass compared to electrons 🤔

[@faridashakikhanli5169]

Yes, i guess so. Electron is 1837 times smaller than proton.

[@anmoldhawan2671]

Mahesh Shenoy , really really thank you

[@whysoserious1150]

I only love your videos!!! pls make more of them!!

[@klevisimeri607]

Wonderful lectures! Respect!

[@rajdeepchakraborty9669]

It's the video whre my doubt is clear actually i was facing problems in finding directions and saw several videos but no one is able to clear my doubt and finally this channel or what I can say you clear my doubt in a very nice way. Well explained...

[@satyansh_sri]

Well explained

[@mariavelasquez1419]

Glad I found your videos. Also, love your enthusiasm!

[@livinglife3352]

Sir, modern physics especially radiation part seems like complicated stuff. Could you please help on posting those videos in your channel. Would be very helpful.
I want to tag this message on everyone of your videos.

[@user-vrushti.v]

You are literally the best physics teacher ever, you make the things soo interesting thank you 🥰

[@rjxxx9301]

why did not you put the negative sign with the e for the charge of electron when you were writing the formula of currrent????

[@oyster4545]

How much logical this person is🥲🥲🥲🥲i wish i can meet him

[@SouvikPaul-bz5sl]

14:07 because of mass of proton is high than mass of e-

[@tenzindorjee7689]

Because mass of protons are higher 👍🏻

[@hdskfneod]

Awesome lecture!

[@i__stand__with__palestine__]

Exactly now my brain accepts thiz 😹....
Thank uh so much for thiz lecture...
Ur voice iz also too magical that it only once sets in mind

[@Gajindrasahu]

Excellent explanation

[@p0intblAnkwaziT]

So to clarify: To explain magnetism, we can use the Bohr Model -- which isn't completely accurate via Quantum Mechanics -- which says electrons orbit the nucleus; this orbiting creates a magnetic moment. However, not only is there a magnetic moment being created about the atom because of the current / orbiting electron, but the electron itself has its own magnetic moment because while the electron is orbiting the nucleus, it is spinning about its own axis? Did I have it correct?

[@BabaBoee5198]

It’s not actually spinning tho. I looked up his spinning video and i clocked it all

[@kritikagupta1548]

I was struggling in this topic. And, oh how fortunately found this great channel ?😍

[@nineteentwentytwo]

AMAZING

[@anilsurjewala3606]

Love your video lectures

[@user-ld8jk4mw1q]

Helped me a lot！

[@babyoda1973]

Dude gets it the things we know vs our silly meat brains is phenomenal 😊

[@prasaddesai7159]

Excellent 👌

[@MuhammadHafeez-mg2mj]

Good concept 👍☺️

[@zy9662]

So electron’s orbits have direction?? If so can it be reversed?

[@prithvikrishna5830]

answer to last question, "mass of proton is large, so magnetic moment is small comparatively".

[@dhanam2216]

As mass of the electron is very less than proton, angular momentum of electron is comparitively greater than proton and thereby it have greater magnetic moment than proton's magnetic moment

[@scrubs3050]

You sir, deserve more views

[@howdy26]

thank you. It helped me a lot

[@greeshmageechu8502]

Thank you so much sir for dis wonderful explanation

[@JAY-xx7zl]

Thank you so much Sir ❤❤❤

[@tansi4924]

this was really great :3

[@kantiankush6786]

Mass of proton is 1800 times the mass of electron so the magnetic moments are small

[@deneshk353]

Due to greater mass of proton and nuetron M becomes neglegible

[@vivekgupta3692]

*_Summary Of The Video :-_*
*Magnetic Moment Of Electron Around A Proton*
* If Everything Is Made Of Atom Then Why Isn't Everything Magnetic ?
* The Origin Of Magnetism Come From Angular Momentum Of Electron
* To Determine The Direction Of Angular Momentum We Clasp Our Right Hand In Such A Way That Our Four Finger Represent Direction Of Motion Of Particle (Not Current) Then Our Thumb Will Showing The Direction Of Angular Momentum.
* In above case magnetic moment and angular momentum will always be in opposite direction.
* Experiments Shows That Electrons Also Spinning Around Their Own Axis.

[@user-mi3de8qe8k]

Because mass of proton decreases its 'L'

[@Exhilarated1750]

No the protons are in a very less area compared to electrons

[@rudrasatw1k]

Since e= +1.6 x 10^-19C, shouldn’t we be taking e as negative as an electron is being considered?? Then won’t expression of magnetic moment come out to be positive??

[@Exhilarated1750]

No

[@i__stand__with__palestine__]

❤️👍

[@qwerty-ke8es]

can i ask doubts

[@taaayyy5745]

No lol
