Let There Be Light: Maxwell's Equation EXPLAINED for BEGINNERS

A set of 4 equations that describe Electromagnetism - in this video, I'll be covering just one of them. Because otherwise, I wouldn't be able to do it justice.
Don't worry, you don't need to know anything more than high school mathematics and physics in order to understand this video (assuming I've explained things correctly lol).
Hey everyone, I'm back from a fairly long break with a video on Maxwell's Equations! I asked you guys on Instagram a couple of weeks ago whether you wanted to see a video on Maxwell's Equations or whether you wanted a video on the model of the atom. Maxwell's Equations won out, so here we are.
Thank you so much if you voted in my poll, and if you don't already then follow me on Instagram (and Twitter) @parthvlogs
So, the Maxwell Equation I'm covering in this video states that the Divergence of a Magnetic Field is equal to Zero. In order to explain what this means and what it implies, I realised I had to describe what "divergence" meant, and in order to do that I had to describe what vector fields are.
So that's exactly what I've done. Firstly, we discuss vector fields and a few examples of vector fields, and then we discuss how to find the divergence of a vector field in a fairly intuitive and visual way (without going too much into the mathematical gore). Finally, we go on to looking at what this particular Maxwell Equation says about magnetic fields, and the implications of this - that there is no such thing as a magnetic monopole (single pole), and that there are no sources or sinks of magnetic field. This is why any magnet will always have a north AND a south pole - even when we cut a magnet into half, we get two smaller magnets which each have two poles. Thus, no evidence of a magnetic monopole exists to this day.
This video goes into quite a lot of detail, so if there's anything that isn't quite clear enough, then feel free to let me know in the comments.
Finally, thanks so much for watching. Feel free to drop this video a like, and subscribe to my channel if you haven't already. Hit that bell button if you want to be notified every time I upload - I make fun physics videos, though I don't have to try too hard because physics is already fun!

About B: Maxwell just used the letters A through H for vectors in his Treatise on Electricity and Magnetism and some of them stuck and some of them didn’t. A is still used for vector potential, B for magnetic field (or magnetic induction or flux density, depending on who you ask), H for magnetic intensity, etc. Maxwell used C and G for other vectors that I don’t recall at the moment. They, for some reason, never stuck.

Vector field: a good analogy of the wind on a weather map. Divergence: bathtub analogy works well. It's many years since I studied electromagnetism, so it's nice to have a fun refresh without all the mathematics. Although, the mathematical equations have powerful applications. A nice follow up subject would be to look at bubble theory, surface tension etc. That has amazing parallels with electromagnetism, yet it is something that everyone can visualise but few would know how or why the soap films behave in those mysterious ways.

That's easy. The one he mentioned is del dot B is 0, that's that there are no magnetic monopoles. Another one is del dot E is charge density divided by epsilon, which is the permittivity of free space, that says that the divergence of electric field equals the charge density. The next one is del cross E is -dB/dt, that is, the CURL of the electric field, which measures how much electric field circulates around in a circle, is equal to the (negative of, but it doesn't matter, if you defined north and south poles to be the other way around, or electric charge to be the other way around) time derivative of the magnetic flux at that point, that is, how much magnetic field changes over time. This is that whole deal where you can generate electricity with a moving magnet. And the last one is del cross B is I (current density) divided by mu + dE/dt divided by both mu and epsilon. mu is the permeability of free space, a measure of how easily it is magnetized, while permittivity is you could say, how good something makes as a capacitor. Magnetic materials artificially raise permeability, for instance iron, while insulators raise permittivity by a factor, and that is what their dielectric constant is, and raise the capacitance of a capacitor with that insulator as its dielectric. When you put these 4 equations together, you can get the wave equation in 3 dimensions, with a speed of the reciprocal of epsilon times mu, which is of course the speed of light. There's a common t-shirt you'll see in physics circles, it says "and god said" and then it lists Maxwell's equations, and then "and there was light". And now you get the joke, if it was ever a mystery to you. I got rid of mine since religious or new age nitwits would come up to me and think I was one of them and it's really not a very funny joke anyway.

What amazes me the most is the fact that Heaviside was a self taught engineer and mathematician . "I remember my first look at the great treatise of Maxwell's when I was a young man... I saw that it was great, greater and greatest, with prodigious possibilities in its power... I was determined to master the book and set to work. I was very ignorant. I had no knowledge of mathematical analysis (having learned only school algebra and trigonometry which I had largely forgotten) and thus my work was laid out for me. It took me several years before I could understand as much as I possibly could. Then I set Maxwell aside and followed my own course. And I progressed much more quickly... It will be understood that I preach the gospel according to my interpretation of Maxwell."

I agree, divB at a point is zero means that the perticular point is neither a source nor a sink. I.e amount of filed lines coming in are equal to going out, i.e. a steady state. This logically concludes that B field lines are in loops with apparant visualization of starting at one pole and reaching the other. This video gives some glimse of div B.

That was good, I"ll be listening to you a lot. When they start using letters in math I was done and I loved math. I had to wait 63 years to hear something that made sense. Good job again.

Great work! Finally Mystics of Maxwell revealed! My fav part of physics is Newton's law of physics It is much simpler than any other And also Einstein's theory of relativity It just breathtaking.

This was a very helpful video, thanks! I'll go look for the others, but I hope you've made videos covering all four, because you just made SO much more sense than my professor just now! And without study parties because COVID19, I really need good videos like this to understand the material. But to answer the question, my favorite thing about physics is that it's just so weird! I love how the universe is infinite, physicists can't agree if parallel universes makes sense as a way to understand quantum mechanics, and just all the other weird stuff that there is in physics. I love being surprised by science and physics has never failed me in that.

One miss if I may call it that is that the water flow is also a div=0 because water inside the tap is flowing like inside the magnet, sorry for nitpicking, but the analogy makes sense!

@MrNerdpwn 4 жыл бұрын

There is no mistake in the explanation. The water leaving through the plug or sink does not come back to the tap or source through some external pipe (at least not mentioned in the video). The tap and plug situation is not like a magnet, it's like a pair of positive and negative electric charges, like electric field flowing from a positive to a negative charge. There is net divergence!

Hey, great video! So I was just wondering what if the circle region you choose for divergence as the whole vector field, for example, the bathtub scenario you gave, what would be the divergence then? positive, negative or 0?

If source velocity and sink velocity match, then div is zero.

When I was in physics class years ago, my instructor covered an equation that explained when a car is driving toward you honking its horn, how to tell how fast it was going. Could you cover that one? Thank you in advance, AWESOME VID BTW!

Integrals are just area under a curve! I wouldn't expect him to make a video of it. Lots of videos elsewhere online!

@AkamiChannel 4 жыл бұрын

The equations of integrals are just the opposite of the derivative. So, learn how to do derivatives, and then look up how to do integrals and u should be good!

Nice video. It's always good to revisit these complex models and relations. One critique: B stands for magnetic flux density or magnetic induction vector, not for magnetic field vector. These are related, but hey, why not using correct terms?

@-danR 2 жыл бұрын

It is largely a matter of preference and convention. See "The *magnetic field vector* B at any point can be defined as..." (B Field, Magnetic Field, Wikipedia.) And: "Alternative names for B: Magnetic flux density Magnetic induction Magnetic field (ambiguous)" ibid. This leeway is without dispute in the article's Talk page.

Wow, a great explanation for those of us with basic education. I actually got it this time! My favorite "thing" about physics is the celestial mechanics equations which predict, with extreme accuracy, the positions of celestial bodies. It's what enables us to sit at home and see pictures taken at Mars, Jupiter, even Pluto & beyond. Amazeballs!
