For the sake of simplicity, I did not go over the concepts of electric and magnetic flux, and was using E/D to describe electric fields and B/H to describe magnetic fields interchangeably to avoid confusion.
Why is B, the magnetic flux density, often used in the place of H, the magnetic field intensity in some lists of Maxwell’s Equations? I hardly ever see H used. I find it confusing when B is referred to as the magnetic field intensity.
Hey Ali, I've been watching you since 500 subs, I'm a grade 12 student in India and I've just finished learning the major part of electromagnetic physics wherein I've learnt about these equations. Thanks for inspiring me to pursue a career in electrical engineering, which I'll be taking next year. Keep up the fantastic work.
I saw the integral versions of these equations when I started studying Physics 2 in my home country Sweden several years ago, and they freaked me out. Thankfully, we weren't actually supposed to know those equations - the entire chapter was just about building a foundation for the equation for light intensity.
150 years summarised in 5 minutes. Like a slap in the face. Whom are you talking to ! housewives? degree students? 1st year ? final year? kids? noobs?engineers? It doesn't seem you have decided yet.. you know your subject well and thats all what the video prevailed..
My dad was a computer engineer and I came across his college textbooks and was reading them and I've recently become interested in how the generally skip over electric fields and teach that electrons move like water or whatever. I designed a PCB board as a hobby I've taken up and I've realized that thinking the power runs through the traces like a water thru a hose causes a lot of issues. There's nothing out there that really teaches electricity from the ground up and it seems like that causes a lot of issues for people down the road
Hey dude! Good to see you here haha. This is actually an awful explanation, I can explain it way better now that I've evolved. I'll be back in LA in August, let's meet up and talk some electronics, I can explain it way better in person
I think another good way to actually understand Electrodynamics better, is by the concept of how simulations solve maxwells equations. (Especially the Finite difference time domain method).
I only made it through the first one since, because you never even said what "divergence" means, I assumed you wouldn't bother with curl either. When I first saw these equations (a long time ago), I "intuitively" thought it just meant the field was spreading out in space. But it's more specific than that, because for some volume containing a net charge, the field is spreading out everywhere, even outside that volume of charge. But the divergence is 0 everywhere outside the charge volume. For there to be divergence only at points where there is charge, requires the field to spread out in a very special way, and it happens that E spreads out that way.
The second law is stupid and unnecessary. It just limits the possibility of a monopole existing, a close-minded law. And no, magnetism is not a byproduct of electricity, it can and does exist witout electricity, permanent magnets, although they do contain electrons with spins.
==== NOT THE MAXWELL'S EQUATION === The "Faraday-Heaviside Framework" is a fitting and just title.

It is well explained💯👍

Wow, thank you for taking the time to write this. This made my morning :-)
Came here to get a refresher on Maxwell's equations, great explanations!

This is my first video of yours. EXCELLENT! I hope you never get tired of teaching; you are uber talented at explaining technical content.
thank you! I actually plan on making an updated version of this!
Thank you! I’m taking EMAG next spring, this definitely made these scary looking concepts seem comprehensible :)
Perfect!!

I Googled Maxwell's equations and you came up, great video!

@@alithedazzling Nice! Yeah hit me up when you're in town!
Extra ordinary and un conventional way ❤❤
Bro cooked the whole topic in minutes❤
His li exercise and meditation to do list ❤
Love this keep posting educational content !!
Glad yuou like it!
That was a great explanation, thank you for this!
You're very welcome!

True, and understanding how different solvers go about it

i have a newer video tha talks about it more intutiively check it out on my channel
So think of charged dc battery for static analysis and alternator for dynamic analysis?🤔
Amazing explanation, thanks man!
Awesome video Ali!
Do more like these
glad you like it!
Nice one !
Glad you liked it :-)
So, if you have a free electron, where is the E field coming from? 😊 Can't really have an E field with an electric monopole either.
Best
First view and like❤️
I love the 80s aesthetic of your channel haha. I am big into synthwave
@@alithedazzling thanks for replying 😊
Im glad you have same taste💜
Actually, electromagnetic fields are belongs to physics, or electrical engineering?
physics -- engineering is the application of physics
@@alithedazzling By the way, as a radiation and antennas designer, do you use in electrodynamics? (that is continuance of electromagnetism)
@@eliran986 yes you have a good understanding of it, but you dont really use it -- you use the tools that use it like hte software

Exactly why math first.😅
Is your nose looks off
Integral forms:
∯D ∙ dS = ∬(D ∙ N)dS = Q
∯B ∙ dS = ∬(B ∙ N)dS = 0
∮E ∙ dr = ∫(E ∙ T)ds = -dΦB/dt = ε
∮H ∙ dr = ∫(H ∙ T)ds = I + dΦD/dt
