1
00:00:09,500 --> 00:00:10,940
Hey, hello guys.
2
00:00:11,000 --> 00:00:11,840
My name is Mr.
3
00:00:11,840 --> 00:00:12,209
Yaro.
4
00:00:12,680 --> 00:00:16,040
And today I want to tell you
about two very strange sticks.
5
00:00:16,760 --> 00:00:17,090
Yeah.
6
00:00:17,450 --> 00:00:18,770
So I actually don't know.
7
00:00:18,770 --> 00:00:23,479
Sometimes they can
behave very very weird.
8
00:00:24,269 --> 00:00:25,630
Sometimes they can stuck.
9
00:00:26,090 --> 00:00:29,950
On the bottom of the cup!
10
00:00:30,610 --> 00:00:33,915
Actually no idea why it's happened.
11
00:00:37,775 --> 00:00:40,315
Actually, the reason why is the magnet.
12
00:00:40,515 --> 00:00:41,885
So this is magnetic ring.
13
00:00:42,335 --> 00:00:43,985
And what do we know about magnets?
14
00:00:44,055 --> 00:00:45,225
What is it magnets?
15
00:00:45,735 --> 00:00:50,339
Actually magnets is special metals
which can attract another metals.
16
00:00:50,660 --> 00:00:57,620
This property can be with materials
which contain iron, nickel and cobalt.
17
00:00:58,220 --> 00:01:00,140
So and we call it magnetic property.
18
00:01:01,310 --> 00:01:06,710
And another materials like
wood, plastic, or even paper
19
00:01:07,635 --> 00:01:10,095
-
they can't have this property.
20
00:01:10,185 --> 00:01:11,695
We can't sticked by magnets.
21
00:01:12,055 --> 00:01:13,075
So check this out!
22
00:01:14,305 --> 00:01:19,195
Here I have a bar magnet
and this magnet can stick
23
00:01:20,985 --> 00:01:25,105
crazy sticks, coins,
24
00:01:29,155 --> 00:01:29,725
paperclip.
25
00:01:32,755 --> 00:01:34,105
And of course my magnetic ring.
26
00:01:35,755 --> 00:01:39,625
But can't stick paper, plastic,
27
00:01:41,925 --> 00:01:44,384
wood and rubber.
28
00:01:47,369 --> 00:01:49,609
So, but let's check details about magnets.
29
00:01:50,220 --> 00:01:52,649
As you can see this
magnet have a two parts.
30
00:01:52,830 --> 00:01:54,119
We call it poles.
31
00:01:54,339 --> 00:01:55,839
North Pole and South Pole.
32
00:01:55,860 --> 00:01:56,670
Like earth.
33
00:01:57,270 --> 00:02:02,880
So, and think, this magnet
can attract different metals.
34
00:02:03,650 --> 00:02:06,390
Using both poles, north and south.
35
00:02:06,390 --> 00:02:10,870
But it also can repeal
using the same poles.
36
00:02:16,980 --> 00:02:17,310
Hold on.
37
00:02:23,770 --> 00:02:27,910
All this attraction happens
because magnets can produce
38
00:02:28,090 --> 00:02:29,440
invisible magnetic field.
39
00:02:29,950 --> 00:02:34,660
And we can't see this magnetic field, but
we can check it using the special frame.
40
00:02:35,260 --> 00:02:37,480
So this frame made of plastic.
41
00:02:37,630 --> 00:02:40,520
And this arrows made of iron.
42
00:02:41,660 --> 00:02:48,709
So and what's happened if we can put
this magnet in the center of the frame?
43
00:02:51,355 --> 00:02:56,635
So as you can see there arrows
adjusted direction and can demonstrate
44
00:02:56,725 --> 00:03:00,595
how exactly magnetic fields happen.
45
00:03:04,005 --> 00:03:06,405
You also can see it
using this, this frame.
46
00:03:06,825 --> 00:03:08,725
This frame contain iron powder.
47
00:03:09,505 --> 00:03:13,404
And if we can put the magnet on
the top of this frame, we can see
48
00:03:13,404 --> 00:03:15,385
how magnetic field can appear.
49
00:03:22,755 --> 00:03:25,005
So now you know more about magnets.
50
00:03:25,605 --> 00:03:26,415
See you next time.
51
00:03:26,564 --> 00:03:27,045
Bye-bye.
