1

00:00:00,240 --> 00:00:04,860

This toothpick is pointing to the material we obtained.

2

00:00:04,860 --> 00:00:05,880

This black spot.

3

00:00:08,700 --> 00:00:09,780

And then...

4

00:00:12,319 --> 00:00:13,929

It's on the screen.

5

00:00:13,929 --> 00:00:16,140

Under the microscope, it looks like this.

6

00:00:17,060 --> 00:00:19,100

Let's magnify it a bit first.

7

00:00:50,020 --> 00:00:52,580

This is a neodymium iron boron magnet.

8

00:00:54,980 --> 00:00:57,460

Then we place this neodymium iron boron magnet

9

00:00:57,460 --> 00:01:00,550

underneath it's material

10

00:01:00,550 --> 00:01:02,300

to observe the material's reaction.

11

00:01:03,580 --> 00:01:07,060

This can be directly extended under the material.

12

00:01:25,320 --> 00:01:26,720

Find the position.

13

00:01:28,220 --> 00:01:29,320

OK, found it.

14

00:01:32,640 --> 00:01:34,060

Adjust the tapping.

15

00:01:38,260 --> 00:01:44,220

Hmm, now our magnet is far below this sample.

16

00:01:44,880 --> 00:01:48,899

Now we slowly bring the magnet closer to this sample.

17

00:01:50,820 --> 00:01:53,060

You can see it's standing up.

18

00:01:54,500 --> 00:01:56,340

We move away from the sample.

19

00:01:58,400 --> 00:02:01,320

Then it falls down again.

20

00:02:02,600 --> 00:02:05,899

We move closer to the sample again.

21

00:02:07,800 --> 00:02:09,139

It stands up again.

22

00:02:11,540 --> 00:02:13,220

Then, move away, and it falls down.

23

00:02:14,880 --> 00:02:19,160

Now, let's change the direction of the magnet.

24

00:02:22,719 --> 00:02:24,800

And then place it under the sample again.

25

00:02:29,800 --> 00:02:32,940

I see that after it gets close,

26

00:02:32,940 --> 00:02:35,120

this test piece stands up again.

27

00:02:36,559 --> 00:02:37,779

And then, move away.

28

00:02:41,019 --> 00:02:42,160

It falls down.

29

00:02:43,200 --> 00:02:46,880

Then move closer, and it stands up again.

30

00:02:48,459 --> 00:02:51,299

Move away, and it falls down again.

31

00:02:51,299 --> 00:02:55,820

Now, I'm directly changing the direction of the pole underneath.

32

00:02:57,920 --> 00:03:00,400

You can see that after changing the direction,

33

00:03:04,240 --> 00:03:05,980

it's still repelling.

34

00:03:09,640 --> 00:03:13,200

Then, as we get close, it stands up.

35

00:03:14,020 --> 00:03:15,960

Then move away, and it falls down.

36

00:03:17,100 --> 00:03:19,200

Move closer, and it stands up again.

37

00:03:20,119 --> 00:03:22,760

Move away, and it falls down again.

38

00:03:28,839 --> 00:03:29,699

It stands up.

39

00:03:32,759 --> 00:03:33,800

It falls down.

40

00:03:36,580 --> 00:03:39,940

It stands up and falls down again.

41

00:03:40,380 --> 00:03:44,520

Whether it's N-pole or S-pole,

42

00:03:44,520 --> 00:03:49,300

the force it exerts on this test piece is repulsive.
