Remember, for mathematical symmetry he is assuming that magnetic charges and currents exist. That way, if anyone disputes your derivation, you can just say let those quantities be 0. Meanwhile if it is found that those quantities actually exists, then you already derived the most general formula. So usually, yes, that term would be 0.
nice videos concept covered exactly i want them to be for my IISc course
This was expertly presented mate, thank you!
Very good explanation professor, thank you.
In @20:56 Divergence of B IS Zero right, so will there be pure surface charge for B?

@@pmcate2 Thank you, got it... 👍
@18:40 there’s no 2pi*r, you already have dS
