1

00:00:00,750 --> 00:00:05,730

It's a great job for making it through the most important section of this whole course, you have now



2

00:00:05,730 --> 00:00:08,210

learned about the Maxwell's equations.



3

00:00:08,940 --> 00:00:15,060

So these Maxwell's equations exist in a differential form and an integral version, and we can motivate



4

00:00:15,060 --> 00:00:19,880

them by symmetry arguments, even though we cannot really derive them straightforwardly.



5

00:00:20,700 --> 00:00:26,250

And you have already learned a few examples where we can reestablish some previous knowledge based on



6

00:00:26,250 --> 00:00:32,280

these Maxwell's equations, for example, we have rediscovered, so to say, the Cullum's law, and



7

00:00:32,280 --> 00:00:37,050

also we have found the missing term in the unpassable.



8

00:00:38,550 --> 00:00:44,280

So now things may still be a bit confusing for you, which is totally fine and totally clear.



9

00:00:44,580 --> 00:00:48,130

And I mean, the rest of the course is still about the Maxwell's equations.



10

00:00:48,450 --> 00:00:50,370

So there's still a lot to learn.



11

00:00:51,150 --> 00:00:57,030

So what we will do in the rest of the whole course is we will discuss special cases of these Maxwell's



12

00:00:57,030 --> 00:00:57,750

equations.



13

00:00:58,350 --> 00:01:05,910

And we will start with electromagnetic waves where we consider basically a vacuum, which means that



14

00:01:05,910 --> 00:01:10,140

our charged density rule and our current density is zero.



15

00:01:11,370 --> 00:01:15,000

Thereafter, we will discuss electrostatic and Magneto's tactics.



16

00:01:15,690 --> 00:01:22,200

This is where we have charges and currents, but on the other side we consider no time dependence and



17

00:01:22,200 --> 00:01:24,210

the electric and magnetic fields.



18

00:01:25,180 --> 00:01:34,000

So these are three different special cases for the electrodynamics and then in the last section, we



19

00:01:34,000 --> 00:01:35,840

will discuss time dependent problems.



20

00:01:35,860 --> 00:01:40,820

So this is where we will really discuss the Maxwell's equations in all of its details.



21

00:01:41,650 --> 00:01:44,380

So for this, we need some prerequisites.



22

00:01:44,380 --> 00:01:47,640

And these are electrostatic and Magneto's tactics.



23

00:01:48,820 --> 00:01:54,070

So let's go ahead and discuss one by one these special cases and then in the last section, discuss



24

00:01:54,070 --> 00:01:55,270

the most general case.
