- Magnetic susceptibility is a measure of how readily materials tend to get magnetized. Diamagnets have a small negative susceptibility while paramagnets have a small positive susceptibility. Ferromagnets have a large susceptibility.
Relative permeability is a measure of how readily materials allow the field lines to pass through them, compared to vacuum.

God’s sent this man.
Yeah
We are also sent by God bro
True 💖
God sent this man.
@@anjubala7815 what abt ur ma?
This guy has an entirely different approach towards explaining physics
Awesome!
The Indian version of Khan academy is superior to the American version
HEY.. I DO NOT COMMENT A LOT. BUT MAN THIS IS FIRE. YOU JUST LET US DO ALL THE DERIVATIONS, THIS IS WHAT RAEL PHYSICS IS. THANK YOU REALLY I CANT THANK YOU ENOUGH
right
Agree with u sir
@2:49
Dood got a strong throat pain after that strong magnetic field xD
Yeah for sure 🤣😂🤣🤣
Here is the Lionel Messi of physics teaching! G.O.A.T.
2:49 😂
Indian with a decent accent that everyone in the world can understand
You made learning physics very intresting. Teacher like you is very rare to find, Thank you❤
After a long time, I had fun learning
Thank you very much
He made me understand the actual physics finally!
Superconductors are the materials X= -1 , below their critical temp
You are an amazing teacher! I got exactly what I needed from this vidéo 👌🏿 thanks
-1 are the susceptibility of super conductors also known as perfect diamgnestism
Really I have not make any comment on any CZcams video except a few cases (may be 1 or Maximum 2) in my 6-7 year CZcams experience but really this incredible man makes me push to make a comment down..... Really Gorgeous, fantabolous way of teaching he is making , absolutely fantastic🎉🎉🎉❤❤❤❤❤❤❤❤
First thing i don't have experince learning in English in my life .but your video is so ossom that i can picked up every word, analyze and make the whole concept in my mind..Thanks for providing learning in better ways ...May i got chance to teache student like you in future❤️❤️❤️
All the doubt's are cleared what a great video I found 🙌
12:40 they are SUPERCONDUCTORS 😌
Thank you for perfectly simple and detailed lectures
Superconductors acts as perfect diamagnets due to Meissner effect
Incredibly well.......
my dad showed me something about magnets that i have never herd talked about or explained. If you have a screwdriver that accidentally gets magnetized to de-magnetize it he would throw it down on the garage floor cement hard tip first we would pick it up and test it and it was no longer magnetized. before anyone tells me it doesn't work. Just to make sure i did it two times last week to show a friend. It Works
That is the definition of ferromagnetic. This channel has a video on it. Ferromagnetic magnets are only magnetized for a short period of time.
the way u explain physics with a smile on ur face i can imagine💕 i just love the way u teach😍😍
OMG I got that topic thank you a lot 🙌
Lit 🔥
Today i gound a person who does not learn or teach physics but live and enjoy the beauty of physics 🙌
sir you teach justttttt amazingggg!!!!
TYSM❤❤
Agar starting se esh channel se padta to kaffi achha rahta 😃
Sir ur just straight up lit....u make these tough concepts very easy
Amazing explanation 👍🏻
WOW! Just Wow! What a cool explanation! Love the physics.
The clarity this man gives
THANKS A LOT SIR
Thank you! Easy and simple explanation!
Sir can you please make one shot videos for 2021 👍🏻👍🏻👍🏻
🔥🔥🔥 efforts man! Appreciated!
Thank you so much
thnks such a great explanation
The way he explains...😂.. I like it
Permeability of antiferromagnetic substances??
You are so great ❤
oh my god u are enough to understand physics. I just love your accent...
Love the way he explains.
Thank You so much ❤️
Superconductors have x=-1 value as they are perfect diamagnets and their relative permeability is 0
Love you!
Awesome
thank you so much you saved me
It really help ❤❤❤❤❤
thanks Sir
Atlast, hope is always here.
Sir pls say ur name we love u
His name is mahesh shenoy 😎..
read description
Thanks man i really need it
12:48 superconductors
He is enjoying 😃😃😃😃😃😃..thats why i am also enjoying ..
thanks sir,so informative and perfect explanation. could you please tell me why there is a magnetic line over diamagnetic? i mean why diamagnetic target does not repel the middle magnetic line?
Those materials with susceptibility is zero is superconductors
Isnt the susceptibility range for Diamagnetic materials -1 to 0
You are amazing
Nice explanation
Superconductor have perfect diamagnetism
It is a superconductor
Wt was that ssstttttrrrrong.....thing?
I didn’t understand about Bo in given diagrams. Can someone tell in a few lines
Is it magnetic field in absence of material (wood, aluminium, other)?
Yes exactly it is magnetic field in absence of material.
No words.
8:22 your hee was so so so ... cute 🥰
X=-1, superconductors
my man a dinosaur 2:48
comic tone
12:37 I did the research and ended up in this video. Hope it helps.

Sorry sir par agar hindi me hota to aur acha rahta
He was in the toilet while teaching this.
Show some respect to your teacher ,he s just expressive so that we could retain more, grow up kid

Thank you so much sir
Awesome
