your lectures are extremely convincing, crystal clear and unmatched. You are indeed doing a wonderful service to the Physics Community and I really thank you for these wonderful lectures on behalf of Physics lovers. I feel that you are a born teacher. Keep it up and uploading more and more lectures. Bye the way I could not see your name anywhere. The physics lovers must be quite curious to know about you. So please let us know or introduce yourself through a video and I firmly believe that it will inspire a lot of budding physicists.
0:30 The picture: The direction of the electric current loop generated by the moving electron is not correct in the video. It should be the other way around.
watched this far, amazing videos... and I would like to suggest that you should make another video of clearing doubts, reference material to the topics this course lead or require, like one guy in previous video wrote in detail about proton as a LEVER, and one another guy wrote about nucleus not having I=0,0.5,1 due to orbital angular momentum....
Looked at dozens of videos, I'm missing something, can anyone help? @0:06 he says the magnetic moment identifies the strength and orientation; but we know a spin up and a spin down will orientate themselves in opposite directions to an external magnetic field. So WHAT DOES THE ARROW REPRESENT? It can't be (say) the north pole of the electron or particle because the arrow can point in ether pole of the external magnetic field, (and North always aligns to South) Yet if you agree the North pole of an electron always wants to align with the South pole of the external magnetic field, and tell me that it is the DIRECTION of the spin, then we would be saying the direction a charge spins is independent of the direction of the North pole. and we know that's not correct either. Finally many use the old excuse, (well its quantum spin, there is no equivalent) "Fine" I say... "so what does the arrow REALLY represent" Can anyone point me in the right direction? Thanks
Arrow represets the direction in which the particle's magnetic moment (or angular moment vector) precess around an external magnetic field. Btw, spin up and spin down are NOT exactly opposite directions in space. Its just a naming convention. That's the mistake u are making I made a separate video on this. If u are interested, u can check it out th-cam.com/video/QHYJ4VpqAvs/w-d-xo.html
The universe is made up of virtual particles carrying mass, electric and magnetic monopoles. Electron has mass, electric monopole and magnetic monopoles. Electron is also surrounded by respective virtual particles. When charge moves, three type of particles occupy each of three separate space dimensions in X,Y and Z direction. The magnetic particles around electron produce orbital magnetic moment. The Electron's own magnetic dipole tries to align with orbital magnetic moment and produce net magnetic moment.
While flipping the screen at 14:34 ,u have exchanged the neutron proton written there. But u haven't changed the g value. So which value of g was correct ,before flipping or after flipping.
The first one is simply angular momenum (momentum(mass into velocity) and how it changes according to a point)to mechanics that is... It's newtonian, applies to daily object in use and follows its defination(see it online). The other one is orbital angular momentum that means: It is specifically derived for the case of quantum system(electron in its orbital) according to the Schronddinger wave equation.
Thank your for your very nice lecture ❤. One question remains for me, though. I don' t quite understand if bevor applying a magnetic field the (lets focus on nucleus) the nuclei spins have statistical distribution. And if they want now to align with the magnetic field. Why can' t they do it. How does stand the quantization stand in the way of that?
Why do neutron and proton have magnetic moments due to spin angular momentum only.... Where is the contribution of orbital angular momentum... And what is the value of g factor for neutron and proton when orbital angular momentum is considered.
You are correct. Neutron is a neutral particle, so it seems it should not have magnetic moment. However, as it turns out, neutron is further made up of fractional charged particles (Quarks) and has a spatial distribution of charge in its volume. So therefore, even though it has NET charge zero, it still has a magnetic moment due to its inner structure
Nice explanation! But is the value of gyro-magnetic ratios and the values of spin magnetic moments of proton and neutron exchanged?( i.e for Proton's value is it written it for neutron and neutron's value is written to proton?)
you are not teaching with excitment sir...Please explain everything with proper visulization...you were just reading from board...physics should be mathematical too, with theory.
Bro don't be a 'nitpicker',look at the quality and his way of teaching and it takes time to write on the board and videos will be lengthy if he starts writing...

In my entire life i have never seen a individual, who explain these complicated topics such easily and smoothly. Well done sir❤
Look up all my videos on Nuclear and Particle Physics in the following playlist : th-cam.com/play/PLRN3HroZGu2n_j3Snd_fSYNLvCkao8HIx.html
That was martial a bit over my head but probably the very best presentation of any material I have ever seen.
Sir you way of talking..way of explaning things is so crystal clear..... amazing and thankyou🙏
Came across this channel, can't believe how great this is!
could you do an EM course soon?
0:30 The picture: The direction of the electric current loop generated by the moving electron is not correct in the video. It should be the other way around.
I also have same confusion. Did you find any conclusions to it.?
Very nice explanation. I was searching for an explanation of this kind in this topic
❤🤗
Sir.u r doing a vvvv good job. This vd is so helpful nd simple to understand this topic. May Allah bless u.
simply awesome!

sir your teaching method is best please write and explain and upload more videos of nuclear physics
you're great at explaining
Excellent teacher, this guy is the bomb.
Great explanation. Plz carry on....
Wow fianally its clear thanku sir😊🙌
Amazing workkkk!!!❤❤
Sir really I had never seen this type of explanation of complicated thing in simple ways. But I request to u make a video on intrinsic property 🙏🙏🙏
Sit please make some lectures on quantum physics and Schrodinger wave equation etc.
Amazing explanation, thank you teacher
11:45 the charge distribution inside the volume of the nucleus or the volume of neutron😢.....confusing
Very nice explanation

Sir pls make a series on quantum mechanics
Nicely explained sir, please upload video for spin and magnetic moment of odd A nucleus
Thank you so much Sir.
Sir, please take a lecture on "Ground state of deuteron."
thank you very much and wish you all the best❤️
sir kindly refer me a reference book to clear these concepts more accurately

Excellent ❤❤.
Sir plzz upload a lecture series on Quantum mechanics 🙏
What about the g in the magnetic moment of a nucleus, what is it equal to ??? Sum of gs & gl or what
Thank you for videos sir .. 👍👍👍

Sir please make video on electric moment also🙏🙏
Sir, thanks very much for the clear descriptions. But the g factor of neutron should be 3.826, and 5.5858 for protron.
yes
Will it interchange the spin up and spin down energy levels?
Cause gn -3.8263
And gp = + 5 5857
Nice video. If possible please enable subtitles.
While flipping the screen at 14:34 ,u have exchanged the neutron proton written there.
But u haven't changed the g value.
So which value of g was correct ,before flipping or after flipping.
After
Question pleae:
Here You said
L =m.v.r
But in previous video
L=√l(l+1) h
Which one is correct?
The first one is simply angular momenum (momentum(mass into velocity) and how it changes according to a point)to mechanics that is...
It's newtonian, applies to daily object in use and follows its defination(see it online).
The other one is orbital angular momentum that means:
It is specifically derived for the case of quantum system(electron in its orbital) according to the Schronddinger wave equation.
Here we are considering the first one
@@saksham5882 Thanks Alot
You are great sir..... 😘
Professor why we are so interested in magnetic moment? and how it shows strength of a magnet?
very good sir
Thanks a lot Sir 😊🙏🙏👍

I don' t quite understand if bevor applying a magnetic field the (lets focus on nucleus) the nuclei spins have statistical distribution. And if they want now to align with the magnetic field. Why can' t they do it. How does stand the quantization stand in the way of that?
sir please... make videos about Solid state physics
May god bless your heart ❤️
Why spin angular momentum direction is opposite to magnetic moment in case of neutron?
11:30 If neutron is made up of some particle then how is it a fundamental particle????
it is not
Hiii... Can you upload magnetic quadrupole moment video
Why do neutron and proton have magnetic moments due to spin angular momentum only.... Where is the contribution of orbital angular momentum... And what is the value of g factor for neutron and proton when orbital angular momentum is considered.
Do electrons complete revolutions around the nucleus?
I think north south poles should be in drawn in opposite direction
Awsm sir👌👌
How are these correction term g determined?
Sir I have a doubt, neutron s are charge less but how it make magnetic moment
You are correct. Neutron is a neutral particle, so it seems it should not have magnetic moment. However, as it turns out, neutron is further made up of fractional charged particles (Quarks) and has a spatial distribution of charge in its volume. So therefore, even though it has NET charge zero, it still has a magnetic moment due to its inner structure
@@FortheLoveofPhysics sir,you mean it is like atom as whole neutral but it possess some magnetic moment s
In a way. It is made up of charged particles i.e quarks, but as a whole is neutral
@@FortheLoveofPhysics Thank s to reply.I know udd is neutron
Sir can you take a class about party,nuclear rotational spectrum
Say what about electric moment plz😢😢
Nice👌👍👍👍👍
It is Excellent explanation . Please , recommend me a good nuclear physics book for beginner ?
You vl find the basics in Modern Physics, by Arthur Beiser. After that you can proceed to Nuclear Physics, by Kenneth S Krane
thank you
why nuclear magneton has mass of proton in denominator only?
Thank you!
Nice explanation! But is the value of gyro-magnetic ratios and the values of spin magnetic moments of proton and neutron exchanged?( i.e for Proton's value is it written it for neutron and neutron's value is written to proton?)
yes i made that mistake initially but corrected in later in the video
May God bless you
sir can you please explain splitting of protons states under magnetic fieldand larmor theorem
hats off to you sir
sir please upload the lecture on accelerators like linear
etc
Uploaded van de graff th-cam.com/video/Q9bijrQfS6E/w-d-xo.html linear acc is next
Thanks you sir!
Physics is fun🎉
Sir what is this orbital angular momentum ? Is it the angular momentum associated with the electron orbiting around the nucleus
What is the mass here ? Is it rest mass or effective mass?
Yes. Orbital refers to revolution in an orbit, as opposed to spinning on its axis. Its rest mass
Sir plz make a video on significance and derivation of correction factor g
Thank you sir
nice
Please post on meson theory
I discussed it a bit while I was talking about nuclear force
th-cam.com/video/43AyN24jZw8/w-d-xo.html
Thankyou sir
Neutron has no charge then how it can have magnetic moment?
Because it has a charge distribution inside (due to quarks)
Channel name signify ,what a video??
Thank you so much sir..I had hard times understanding all these concepts. But now it is very much clear to me.🙏
Sir, what will be the orbital magnetic moment due to alpha -shell electrons in atom?
Yes you are right but make small video with writing than explain.
you are not teaching with excitment sir...Please explain everything with proper visulization...you were just reading from board...physics should be mathematical too, with theory.
