- 021 - Magnetic Dipole Moment
The magnetic dipole moment is the torque experienced by a material placed in a magnetic field. The magnetic dipole is an intrinsic property at the magnet, domain, atom, and electron level. A magnetic dipole creates magnetic fields that connect the north and the south poles.

The simplest straight forward explanation I was able to find. Thanks a bunch
Thank you, your explanation on the domains made it very clear to me how the domains are related to the spin of the electrons. 10/10
@ 4:15, Co = Cobalt, not Copper (Cu), otherwise this was a good lecture snippet.
One of the best 5-minute explanations, perhaps of ANYTHING, on CZcams
Awesome info as always. You are a great teacher.
The dipole model at 2:30 it's good to understand magnetic dipoles, however it's not physical, since there are no magnetic monopoles, or at the very least we haven't found them
The video is really very helpful and explanatory!
the best teacher in the universe
Great video! It helped me a lot.
Loved Your Explanation !
Thank you very much for the lectures
You are a savior :)
Thank you, Sir.
You are brilliant at explaining physics, I have learnt so many things from your videos.
Thank u for uploading this videos....
hey dude u are so helpful and superb r
ur every video is brilliant and I smartly learn from it thank u very much
It was helpful, well done.
That was helpful ... Thanks
very helpful! thank you!
Superb explanation.
Very clear and interesting explanation. Continue this nice explanation.
Awesome cleared my doubts and now have the concept very clear
Thank you for information
great video! you are a good teacher
Thank you so much, Sir.
Bless you bro
Thank you.
THANK YOU
thank you sooo much
thank you so much
Thank this answered all my questions. 😘
does negative charge always contains north pole
and negative charge contains south pole of a magnet?
The way u explained was excellent, I really liked it and enjoyed it .. nice explanation. ....... thankyou soo..... much for your efforts to make it understood. ....... lovely...................
awesome.....thanks sir...
Thank-you sir .
excellent!!!
So when the North Pole or Dynamo moves all the shell material(and filler)has to move magnetically also correct? Or does the material stay exactly in place just the magnetism changes? I would think that the rock would move causing more earthquakes, volcano's an the like over an extended period as the Earth adjusts?
thank you
Thank you soo much. This video was really helpful in clearing my concept about magnetic dipoles.
But I have some doubt on the "what are domains" and how they line up in the presence of a magnetic field.
can u please clear my doubts, sir??? please
great job
@4.16 It could be iron copper nickel.... and showed symbol of Co-- Cobalt :) rest of lecture awesome :)
Copper is diamagnetic, when energised the dipoles oppose the magnetic flux which results in a repulsive effect rather than an attraction. This property makes it a good material to shield things from electromagnetic interference.
@@MCFC69 magnetic flux..? That's basically like the number of magnetic field lines in a give area, right....?
Great video. Maybe you can help me with something: For years now I've been trying to figure out why it called a magnetic "moment"? I've asked around and searched for answers and have yet to find anything that actually answers the question. I can see it being called a "force" or a "torque". But why "moment"? I can't wrap my head around the reasoning.
Look up the definition of a moment.
Moment is related to angular displacement and it depends upon relative orientation of magnet to externally applied field....when it is placed in external magnetic field it deflects to align itself in the direction of external field......this deflection is result of torque which is experience by the magnet...
He meant cobalt not copper but that's OK. Copper identifies as diamagnetic. Great video. Your a great teacher.
Thanks
Are the dipoles between the nucleus and the electrons?
well...thts smthng called help full....thnx fr ths one...
omg ur spelling is so bad i don't know from where to start
@@kailuigi3793 dude just stfu
Please, Is it posible the magnet changes the pH? Thanks
🤔At room temperature these domains are partially aligned or complete alignment?
Correct
Hiiiii ❤️❤️❤️❤️❤️❤️ plz explain about magnetic dipole moment in detailed manner and which book explains well about it plzzzzzzzzz help me 😭😭😭😭😭❤️❤️❤️❤️🙏🙏🙏🙏
Yeah! exactly!
2:20 conventionally those electric field lines should be drawn from "negative" to "positive" correct? Not the way it was drawn in the video, since charge is electrons and electrons move from negative to positive terminus?
Although the true flow of electricity is the electrons moving from negative to positive, the convention is actually the opposite. So when talking about flow, current, or electric field lines the convention says to go from positive to negative.
ok but how is it that the boundary is so absolute, like its not a gradient, like why is the boundary or how is the boundary so sharp? is it always going to be even like that, is there a lopsided magnet? where a magnet favors more north than south and vice versa?
It's helpful
2:41 there is no such thing called magnetic charges.....
can u maybe explain what did u mean by two charges ?
Magnetic poles are called magnetic charge - seriously everyone know this term 😂😂😂
obviously you dont understand it @@tinaparida1587 his Question was justified cause he exlains it wrong
Graet men
Technically, referring to magnetic “charges” is completely inaccurate. There exist no magnetic “charges” because there are no magnetic monopoles, as there is for electric charges. Also, any material has the ability to become magnetized, at least temporarily under the influence of a strong magnetic field, but of course, for most materials, it takes a substantial magnetic field to do so, hence magnetic levitation"
How do you calculate the magnetic field from a magnetic dipole Moment?
(µ0/4π)[M(3cos^2θ+1)^1/2]/ d^3

Wow :D im in love with this video jaja :D
You are from Spain? /your mother toung is Spanish???
yes
why only lone pair of electrons is responsible for the atomic dipole moment
Because their energy state is free energy state.....and mostly lone pairs are property determinant.....
Bozy the gr8
You stated: electric dipole is two charges then a magnetic dipole is two charges that are magnatized and left it as that. Are electric dipoles not magnetic? if so why not? I understand Magnitism is produced by the motion of electical charge. When are these electrons moving?
Komara Bhargavi Priya why does the definition state that magnetism is the phenomenon caused by moving charge?
@@michellemunoz2591 just accept it and move on lady
Is nucleus a magnetic dipole?
I'd say the protons that make it up are dipoles. Not sure about neutrons though
czcams.com/video/TgXSBu7cYEc/video.html This is what brought me here
So you are saying that the North pole defines the direction of the magnetic dipole moment.
And by extension, all magnetic dipoles should line up pointing to the south pole of the external magnetic field.
And the magnetic dipole moment has nothing to do with spin.
So if all these there are correct... GOOD JOB!
If not, then all you did was confuse anyone who is is interested in magnetic dipoles.
This isn't right. There is no such thing as 'magnetic charge'; magnetic monopoles have never been observed despite centuries of effort to create them. Your diagram of the magnetic field should have looked different to the electric field because magnetic fields can only ever be loops (no charges!) whereas electric fields can be as you showed them: with charges acting as sources or sinks for the field lines.

Thank you! I thoroughly enjoy your teaching style. Also, Copper is not Ferromagnetic, that is why a penny, even without its 5% zinc, cannot be picked up with a magnet.
en.wikipedia.org/wiki/Category:Ferromagnetic_materials
yes, i think the speaker meant to say "iron, cobalt and nickel" but by a slip of the tongue said "iron, copper and nickel" while looking at the overlaid graphic which was showing "Fe, Co and Ni".
innocent mistake.
Alpha!
Too basic---should have shown what a magnetic moment really is. The cos of the field etc.
Why are u so handsome..😇😇😇😊😊😊😊😊😊😊😊😊😊😊😊
please speak slowely
U can adjust the speed according to ur preference ... Just click on that 3 dots above the video and then choose the speed fron "speed" section. Thanks !

bad vid: you explaining Nothing at at, for example: what is a Domain, what is magnetized and what are you saying About the North and South pole is wrong
Am I the only one from 2023
