First of all thank you! Everytime i am confused i search for you and rejoice when i hear your voice. Not only are you an amazing teacher but your enthusiasm and passion for the subject in infectious!!! You literally get me excited for physics!! Secondly what is your name and do you have any other science channels?
Curie point at which ferromagnetic material goes from being ferromagnetic to paramagnetic. Thank you very much. I like the way you explain all this in a simple illustrated way ❤
Wonderful video! It's very informative(duh!). Thankyou so much❤. I just have a small doubt(although I am not sure if it has already been discussed in the video) - if the Curie temperature of Gd is 20 degree celsius, wouldn't it be just a paramagnet at room temperature? Is our classification of magnets into dia, para or ferro based on room temperature? 🤔
Magnetism is dipolar only. How does a globe Earth have two external opposing poles while containing a neutral core? A sphere should have a field that is either entirely internal or a neutral external equator to converge opposing external poles. Why is Earth described as tripolar while we know there is no such thing as a magnetic tripole? I say it's because the Earth isn't actually a globe while we have been lied to and deceived along the way.
Exellent video. I just have one question. Lets say i have a thin bar of 100.000 tons of gadolinium at 19,999999°C .Above this bar i have a magnet(BIG one) who then lifts the bar. Now i use my small candle in the bar just to raise its temperature to 20°C so it falls. Now i wait a little so the bar comes back to 19,9999 and alll the 100.000tons goes back up. Obviouly something is missing since i cant lift 100.000 tons at will just with a small flame. My question is : what is missing?
For anyone still curious, the reason that the magnetic moments align in the domains is due to the Pauli exclusion principle. Energetically, it is more beneficent for the magnetic moments to align in the same direction, than it is to align in the opposite direction. By the exclusion principle, magnetic moments that are aligned in the opposite direction can be closer to each other, but this results in higher Coulomb energy. For the less Coulomb energy, the magnetic moments need to align the same way to be further away. Edit: also, it's not the domains, that align, but the boundary of the domains expand. Domains where the magnetic moment is in the direction of the external magnetic field expand, while other domains shrink
I searched a little about it and the element Neodymium has a curie temperature of -240°C so they behave as paramagnetic at room temperature... Also the Neodymium magnets are made of an alloy of iron boron and Neodymium
Not "one of the best", It is "THE BEST" explanation of the above mentioned topic so far I have seen or found.
I don't know how much should I thank him simply amazing 🤩
8:19 curie temp is termed after Pierre curie
Great video, now i more understand about this topic. Thank you sir
incredible explanation...thanks a lot
I felt relieved when the magnetic domains appeared again below the Curie Temperature.
Me toooooooo!!!

Mahesh Shenoy channel name floatheadphysics
You are an amazing teacher, keep up the great work. Knowledge is power.

Thanks a ton, sir. ♥️
✌️..
thanks sir
your vedios are helpful for my jee preparations , thankyou waiting eagerly for ur vedios
8:19 its named after husband perrie curie..
man your teaching skills are damn too awesome!!!!
very good explanation
Most of the teachers teach students just to score marks in exams but, sir you made me to understand concepts . Thank you so much sir🎉
Thank you! Really informative!
No words to praise ✨
Thank you
You are amazing.
Great work❤
Thank you sooo much! Like a pro.
Thank you for this brilliant video.
Ooo my god ...... incredible lec ❤ thanks for this
very well explanation, easy to understand 👍
Thanks Mahesh
bravo ! the content is just superb
Amazing explanation..
A big hand of applause from by core of heart sir thanku so much 😊
Thank you for this perfect explanation.
Thank you for the video. Amazing 😍
Thank you, saved me
what's really important is not actually explained. WTF are domains formed in iron, but not in Aluminum ? Thats what should be explained.
He did say its explained in higher studies (quantum mechanics)
Amazing video 👍🏻
Thabk you so much for your presentation is it possible to know the application to do this presentation. Thank you in advance
best teacher of khan academy
Great explanation, thank you brother!!
Thank you so much Sir. Very Beautifully and Greatly Explained Sir. Love from Pakistan 🇵🇰 ❤.
Arigatau Sir 🙏
Thank you so much Sir 😢 Finally I understand it ☺️ after watching the so many vedios 😢
Bhai boht hi maaza aaya 🌚☺️👍🏻
Film dekhi kya😂😂aise bol raha hai
Thank you, you are awesome ❤
Are the pockets of magnetism in the iron really quantum related? Or is it related to the crystalline grain structure of the iron?
Great explanation

Thanks allot sir
waw Great!
Amazing didactic!
Thanks a lot.
Thanks a megaton , sir
For more details look at the Ising model!
THANK YOU!!!!!!!!!!!!!
Thank you
Is there any explanation on antiferromagnetism and ferrimagnetism?
YOU'RE AWESOME !
Are all paramagnets just ferromagnets with a low curie temperature?
No
Thankyou.
You said that if we low the temp the it help to aline magnet but in low temp is there any chance that it get freezed
Very nice explanation 👌🏻
Love from Haryana
2:25 plz link me to why this happens with iron
Nice explaination
Can you convert a soft ferromagnet to a hard one? If so how?
Awesome
Is the reason the other metals are also called Ferromagnetic, just because they "act"like iron?
3:50 5:05
Peri curi
So that's why soft iron are called that way... Damn
Wow...
Thank you sir, So the atoms in the material themselves act like tiny magnets?
standing ovation
Sir please write formula also we will get help to solve related question🙏🏻🙏🏻
Not soft in d sense of of a pillow got me laughing...
sir curie's law deleted hai na 2024-25 ke syllabus mein
And the earth core
Holy shit this is good
CL de mim ir no ER e ER ET r viu se fala alguma novidade sobre as coisas
what is your name sir ?

I am pretty sure that you have got no replies since your question speaks the language of gods. 🙄🙄
your question is missing logic. it first of all would be very hard to come by a 100tons of Gd and so goes with the other numbers you mention.
@@divyjunnarkar2788 thanks man. I guess no one rly knows or, like masuka, didnt understand. Lol
@@filipenegreiros9557 but it was really interesting of a question dude. So bad i don't have its answer but it seems very amazing of a thought.

What about the element Neodymium? Wouldn't that fall under the ferromagnetic category? When you purchase Neodymium magnets, they are insanely strong.
I searched a little about it and the element Neodymium has a curie temperature of -240°C so they behave as paramagnetic at room temperature... Also the Neodymium magnets are made of an alloy of iron boron and Neodymium
@@dodokoi036 yeah I found that out later, that they are actually alloys
Really very helpful
Thank you so much Sir😊
