Professor what you explained is much more understandable than what my university professor did! Great explanation! Thank u!

[gerardarriola]

Love to see the concise mathematical derivation that most videos would skip 👍

[ArcherOfJustice]

I've got a PhD in electrical engineering and this is the most clear explanation I've ever seen

[ArpanModak]

You summarized the whole lot textbook proof into an easily understandable concept.Thank you

[osamaalsheikh]

Again I am speechless, this is easy abstain. My professors should be ashamed of themselves. Thank u

[shreyashukla]

This saved me. You made it so much easier, thank you.

[idilyaktubay]

this made everything so easy! such a concise and clear explanation. Thank you so much for this!

[zedflintoff]

A lifesaver. I needed an oversimplified picture for now. Really helped me for the time being. Thanks

Hi, I would like to ask why do we bother to create the concept of A which in the end is a formula related to the current and then we take the curl of it to get B, when we can use Ampere's Law which is the curl of B = mu0*J in statics and vacuum? If we want the vector B, can't we just use integration on the curl of B instead of doing the Magnetic Vector Potential approach?

[satranc_kaplani]

Hi professor, thank u. But I have a question. Why didn't you consider dD/dt for ampere's law

[kevinwood]

great information! I wish you could have slowed it down more though the video

[SalamaOmarSalama]

Your beauty made me understand without thinking. Thank you, beautiful woman

[ujjwalkumar]

Crystal clear explanation of vector potential, thank you for this.

[hermolaoutube]

Well in the Poisson equation for A we have a scalar on the left by definition, but a vector of J on the right, how come?

[ahmadebrahem]

Thank you very much for making it so easy

[johannesd.]

This was a great explanation! Thank you very much! :)

Waaaay better than the Griffith's explanation.
tldr *Helmholtz does the **_heavy_** lifting here* and cuts from the Divergence factor from the expansion of *∇* × *∇* × *A* = *∇* ( *∇* ⋅ *A* ) - *∇²* *A*

Quantum energy photon linear force deviation sine transverse waves and deflection into 100% elastic collision/propagation at 'c' in free space is 100% captured by quantum electron in orbital shell of the atom.
Zero in the atom is the graviton into which is the magnetic field curl (in a vague sense).
It's a solenoid in free space that gets its potential from incident photons.

So unlike electric potential, magnetic potential is for mathematical convenience and it doesn't have a physical meaning. Please confirm my understanding.

[amandabankai]

Wrong. It's not just a mathematical construct.
