Observing the magnetic reaction of a material under a magnet using a microscope
Subtitle language:
00:00 → 00:05
The toothpick is pointing to the material we obtained, this black dot.
00:08 → 00:16
And under the microscope, it looks like this on the screen.
00:17 → 00:19
Let's zoom in a bit.
00:30 → 00:52
This is an aluminum shed magnet.
00:52 → 01:02
Then we place this aluminum shed magnet underneath its material to observe the reaction of the material.
01:03 → 01:07
This can be directly extended underneath the material.
01:22 → 01:29
Let's find the position. OK, found it.
01:32 → 01:34
Adjust the focus.
01:38 → 01:44
Our magnet is now directly below this sample, but it is far away.
01:45 → 01:49
Now we slowly bring the magnet closer to this sample.
01:50 → 01:53
You can see it standing up.
01:54 → 01:56
Now let's move away from this sample.
01:58 → 02:01
And then it falls down again.
02:02 → 02:05
Let's bring it closer to this sample again.
02:07 → 02:09
It stands up again.
02:11 → 02:13
And then it falls down when we move away.
02:14 → 02:19
Now let's change the direction of the magnet.
02:22 → 02:25
And then put it underneath again.
02:29 → 02:35
After it comes close, this sample piece stands up again.
02:36 → 02:42
And then it falls down when we move away.
02:43 → 02:47
And then it stands up again when we come closer.
02:48 → 02:51
And then it falls down again when we move away.
02:52 → 02:56
Now I'm going to directly change the direction underneath.
02:57 → 03:00
You can see that after changing the direction, it is still magnetic.
03:04 → 03:06
And then when we come closer, it stands up.
03:07 → 03:11
And then when we move away, it falls down.
03:12 → 03:14
And then when we come closer, it stands up again.
03:15 → 03:17
And then when we move away, it falls down again.
03:18 → 03:20
It stands up.
03:27 → 03:28
It falls down.
03:31 → 03:32
It stands up.
03:36 → 03:37
It falls down.
03:38 → 03:39
It stands up.
03:40 → 03:44
Whether it's N-class or S-class, it has a magnetic force on this piece.
03:44 → 03:49
It's magnetic.
