Hello everyone. Welcome to

Introduction to In-depth solutions

for Maxwell's Equations.

This will be the last part of

our electrodynamics

and its application series.

My name is Professor Seungbum Hong

and to my right side,

we have my teaching assistant,

Melodie Glasser.

So, let me introduce ourselves.

I myself is a professor at

KAIST and alumni of

KAIST as well as visiting researcher

at Argonne National Lab.

Melodie Glasser is a student at KAIST.

She will receive her

master's thesis this year

and she's also

a Colorado School of Mines alumni.

So, KAIST is a University

in Korea and the mascot is nub-ju-gi,

and you can see the symbol

of the university.

The location is in

South Korea and you can see

this red spot which is Daejeon.

This is Mecca of

science and engineering of South Korea,

the next, we can see the table

which lays out the overall structure

of our lecture series.

So, you can see if you're here,

you're already check number

one and number two and number three.

Congratulations.

So, the last part of our journey is

named Electrodynamics In-depth solutions

for Maxwell Equations.

So, you will spend

five more weeks with us to

finish or complete

the lecture series. So, Melodie.

Yes.

Among those four,

which one is your favorite?

I like the electric and magnetic fields

one because it really

started coming together and we can see

the larger practical

applications like generators,

but number four is also great.

So, I'm excited to go

through that with you guys.

Very good. What is

your choice, I'm very curious?

So, with that question left behind,

let's see what we will cover.

So, we will firstly recap what we have

covered before including the scope

of the first two lecture series.

So, Melodie, can you tell our students what

we did in the previous past two lectures?

Yeah. So, what we focused on

a lot was like the visualization.

So, we talked about like,

how can we use scalers or vectors or

mapping or something to

visualize our field and then

we also did derivation.

So, we told you a lot

of mathematical and ways

to come up with solutions

for many different scenarios.

Then, we also have taken

a look at the full picture.

We talked about the micro-scale forces

between atoms and then

we talked about the macroscale

which is forces in capacitors.

So, that's just in

the first two lecture series and

then we also did more and the third one.

Exactly. We covered vector fields,

scalar fields, how to visualize them.

We also covered micron scale to macroscale.

So, we covered multiscale physics

in the previous past lectures.

Now, this third lecture series,

you have probably understood how

magnetic fields are created

by rotating current around the loop.

You also were able

to apply that knowledge to

generators or motors that you

can see on the right side of the picture.

Now, we've got still more to learn.

So, in the final part

of our lecture series,

we will get seriously

into the Maxwell equations in

free space and also with

charges and currents as the sources.

We will also cover

the wave equation which

will describe the fields

as a function of space and

time and we will have

a lot more equations like the one that

is written here to

understand the underlying physics.
