I like your lecture so so much so do well to always ensure that your writing is legible on the marker board .Not hand writing but clarity on the board due to type of marker or the board
@@munawaralijamali4521 yes exactly..it's the group of atom which shows or align in a common direction...and I think there will be many domains in the substance with it's common direction
How the flux density inside the core gets fixed after all magnetic dipole moments get aligned. B = B0+B magnetization B0 still increases as we increase the current even B magnetization gets fixed. So, how B becomes constant when all domains are aligned as the B0 can be increased
Let us assume this example: Before applying the external flux (B0), all domains are random such that the net flux density (B magnetization) is zero. Now we apply B0, the domains starts aligning in the direction of B0. We increase B0 till all domains get aligned in the direction of B0. At this point, B inside the core which is equal to B0 + B magnetization gets constant. But, we can still increase B0 , so how B becomes constant in the equation above since B0 can be increased as it is proportional to the current flowing in the coil that is wound on ferromagnetic core. Thanks
Brother flux density will remain constant as we know the formula of B=phi/area of the core.so area remain the same in any material take an example of transformer the magnetic circuit area is same so flux density remains the same.

What a way to deliver......impressed.
Started learning from u from class 11, now in 2nd sem id bsc
Brilliant explanation sir🙏🏻
Nice explanation sir, thanks a lot.

Sir what is domains
Yuuygggyu
Domain means group of atom

I love you sir 😘
Thank you so much sir ,
Your lectures always been so helpful in understanding every concept of physics clearly
If he had taught me during jee preparation I wouldn't be in agriculture field now😂
❤️da
Very good
Iiiiiiiiiii
How the flux density inside the core gets fixed after all magnetic dipole moments get aligned.
B = B0+B magnetization
B0 still increases as we increase the current even B magnetization gets fixed. So, how B becomes constant when all domains are aligned as the B0 can be increased
Due to Saturation.
@@ashishkumarsharma1323 exactly. It reaches maximum value. Don't worry you'll learn a lot about these in higher classes.
Nice

It reaches a max value.
