It's a great job for making it through the most important section of this whole course, you have now
learned about the Maxwell's equations.
So these Maxwell's equations exist in a differential form and an integral version, and we can motivate
them by symmetry arguments, even though we cannot really derive them straightforwardly.
And you have already learned a few examples where we can reestablish some previous knowledge based on
these Maxwell's equations, for example, we have rediscovered, so to say, the Cullum's law, and
also we have found the missing term in the unpassable.
So now things may still be a bit confusing for you, which is totally fine and totally clear.
And I mean, the rest of the course is still about the Maxwell's equations.
So there's still a lot to learn.
So what we will do in the rest of the whole course is we will discuss special cases of these Maxwell's
equations.
And we will start with electromagnetic waves where we consider basically a vacuum, which means that
our charged density rule and our current density is zero.
Thereafter, we will discuss electrostatic and Magneto's tactics.
This is where we have charges and currents, but on the other side we consider no time dependence and
the electric and magnetic fields.
So these are three different special cases for the electrodynamics and then in the last section, we
will discuss time dependent problems.
So this is where we will really discuss the Maxwell's equations in all of its details.
So for this, we need some prerequisites.
And these are electrostatic and Magneto's tactics.
So let's go ahead and discuss one by one these special cases and then in the last section, discuss
the most general case.
