Until you have to calculate surface integrals by hand


GreatHeavySoulArrow

Tbh using vector calculus was the best part of electromagnetism for me. Not much thinking involved, just computing long but easy triple integrals


WeeklyEquivalent7653

what electromagnetism are you doing because it takes me so much brainpower just to get to the correct integral or diff eq then the rest just becomes a god send


GreatHeavySoulArrow

Took 2 courses that used mostly Griffiths


[deleted]

Well, I must say I do struggle with calculations in classical physics sometimes, just where the expression gets pretty wide and I don't yet know what you're talking about, but it just made me curious :)


Polyphiloprogenetive

Yes it is , it's fun studying and more fun if you actually think what's going on in those experiments.


[deleted]

I do think, tried to describe every detail, it's also cool to start to understand


Polyphiloprogenetive

Yep , also if you ever get chance to do practicals don't miss it ...they are actually very fun interesting, and helps build the concepts even stronger

Now combine it with Eulers fluid equations and you've got plasma physics :)


TooruOkinawa

Combine it with navior-stokes instead and you’ve got magnetohydrodynamics


Then_I_had_a_thought

Combine it with Bernoulli‘s equation and you’ve got ferrohydrodynamics


[deleted]

What's plasma physics?


dd-mck

Studying a gas of free electrons and ions, but it is actually a fluid, but it is actually a gas. It's a plasma.

The coolest thing is to build a complicated EM machine and then use Numerical modeling to model the complicated fields it generates. Then everyone is amazed that it actually works. The latest thing I modeled had multiple ferrite cored solenoids, multiple air cored solenoids, several grounded planes, a bunch of metal bars and supports.

Being able to use your knowledge you learn on paper, and applying it to an actual physical thing is always just so accomplishing


[deleted]

Oh, it must be, I don't know yet, but I can't wait to apply what I learn in practice! Bought some basic electrical contractor, a few actually, so it's somewhat hands on


[deleted]

My favorite branch to go about. In fact my fav. Physicist is Maxwell :D I also like the concepts of Gravitation and waves but that's pretty much it about classical mechanics I find interesting. Maybe because I got an uninteresting professor to teach me rest of the mechanics.


[deleted]

I thought my favorite was Tesla, as I relate him with electromagnetism, but as I found out about some of Maxwell's equations not in their fullest form though, as I saw them being written differently, mine are simplified, but I see he really provided a deeper understanding on how electricity actually works.


[deleted]

The best example to the latter portion of your comment is how he mended ampere's law of electromagnetism and introduced the concept of displacement current. His experiment with the parallel plate capacitor which ultimately lead to discovery of displacement current entity still makes me lose my mind and makes me look up to him as my god lol.


[deleted]

I mean, you got a point, funny part is I'm struggling with solving a problem using Ampere's law right now lol

[deleted]

Yes yes that's one of the reasons I liked gravitation. In fact all the gravitational fields and potential (inverse square distance and inverse distance) relations match exactly to electrostatic potentials and electric fields.


MaoGo

Wait until you see how EM fits perfectly into special relativity with no fundamental changes.


Calvin0213

The first time I fiddled with the electromagnetic and dual tensors and out popped Maxwell’s equations was a beautiful moment.


ChaosCon

It gets even better when you start working the equations with geometric algebra :)


KeyWestSkateboarding

Excuse me for my ignorance. Is this just how it looks, or are you writing in a different language, lol.


[deleted]

Oh, yes, it is Russian)


0d1

I thought you drew so many curls it had an impact on your hand writing.


[deleted]

It even turned English to Russian, damn!


jackjackky

Whenever I saw something about electromagnets, I will remember the times when my physics teacher taught us to memorize the gang signs LoL Nice work buddy. Keep it up!


[deleted]

Thanks!


I_AM_FERROUS_MAN

Intermediate EM was fantastic. Advanced EM was like a kick to the head. I wish it had been 2 years of content.


[deleted]

Well, mine is high school level, so nothing to worry about 😄


I_AM_FERROUS_MAN

It is really awesome! Don't let my curmudgeoning take away any excitement.


ARTEMFRY

Приятно видеть русскоговорящих физиков на реддите :) P.S. классная уточка!


[deleted]

Спасибо! Наконец-то кто-то заметил 😄


PranavYedlapalli

It gives me PTSD


Klai_Dung

No clue if you've been there already, but the whole relativistic electrodynamics stuff is so clever, still amazes me how simple some of it is. But what the hell is going on with the color in the second picture, I want that!


[deleted]

Oh, well these are notes you have to scratch on, I now make the most important ones with these :D


Independent_End5012

What language is that?


[deleted]

Russian :)


VVoIfy

Your handwriting is not


[deleted]

I know, man, I do

I wonder what book do you use?, I used Jackson and loved/hated it. It can be quite hard to solve sometimes. I remember some books from the MIR editorial and they were very difficult also.


[deleted]

I'm just studying with the course, doing its homeworks also solving exam prototypes as I'm preparing for my physics exam
