1

00:00:00,690 --> 00:00:04,530

So that's great that you completed this difficult lecture about electrostatic.



2

00:00:05,740 --> 00:00:11,020

Now we want to consider different special case, which is called Magneto's Static's, so instead of



3

00:00:11,020 --> 00:00:15,550

considering only the electric field, we will now consider only the magnetic fields.



4

00:00:16,150 --> 00:00:21,340

And instead of charges, we will consider Currence, because when you look at the Mexicans equations,



5

00:00:21,340 --> 00:00:27,960

you will see that the magnetic fields are generated by currents instead of charges.



6

00:00:29,020 --> 00:00:35,110

But besides that, to be honest, the magnetic static case is quite similar to the electrostatic case.



7

00:00:35,560 --> 00:00:41,320

And you will realize that when we go through these individual lectures, I will often refer to electrostatic.



8

00:00:42,100 --> 00:00:48,940

So even though you may not realize this right now, you already know a whole lot about Okonedo Static's.



9

00:00:49,880 --> 00:00:55,970

So we will talk about the Maxwell's equations of Magneto Static's, where, again, some terms will



10

00:00:55,970 --> 00:00:56,580

be zero.



11

00:00:56,870 --> 00:01:00,580

This will be the time derivative of the electric field in this case.



12

00:01:01,490 --> 00:01:08,930

And then we will introduce a so-called vector potential instead of an electrostatic potential, and



13

00:01:08,930 --> 00:01:13,590

we will then derived to formula for the magnetic fields instead of the electric field.



14

00:01:14,750 --> 00:01:17,170

So then we can solve several examples.



15

00:01:17,180 --> 00:01:23,270

For example, we will calculate the magnetic field of a straight wire and we will consider current loops



16

00:01:23,270 --> 00:01:24,890

and magnetic dipoles.



17

00:01:25,490 --> 00:01:30,170

And then we will discuss the forces and the talks that act on this magnetic dipole.



18

00:01:31,030 --> 00:01:36,970

And the very last lecture will be a comparison of electro static and Magneto's text, and you will see



19

00:01:37,750 --> 00:01:42,880

it's really the same the same mathematics, but a bit of a different physics.



20

00:01:44,140 --> 00:01:45,750

So I think you can be quite motivated.



21

00:01:45,760 --> 00:01:48,490

And let's go ahead and discuss aesthetics.
