hello everyone especially to Elena and Sergio here is my explanation for your 00:00:02
question let's see if I can do this from home to explain you okay here I have two 00:00:09
magnets okay as you had the same like a bottom they are very flat and round and 00:00:15
And the first thing with these magnets, to explain you this better, is to know here where 00:00:23
is the North Pole and where is the South Pole in each one. 00:00:35
How do we do this? 00:00:40
With a compass. 00:00:41
Just take a look. 00:00:44
Ok, here we have a compass and as you can see the North Pole is here and the South Pole 00:00:49
is here. When we put our magnet here, can you see how the compass is attracted by the 00:00:56
magnet? As here is the North Pole without the magnet, and we put it like this, that 00:01:07
That means that this part of the magnet that I'm pointing at is the south, because the 00:01:25
south attracts the north pole. 00:01:31
What happens if I just turn around? 00:01:36
Can you see that now the south pole is the one that is being attracted by the magnet? 00:01:40
So that means that this part of the magnet is the north pole. 00:01:46
Look, if I turn around, it attracts the North Pole, now the South Pole. 00:01:51
That means that this one is the North and this one is the South. 00:01:59
So what I'm going to do is to write with letters. 00:02:07
So this one is the South, so we write the S, and when we turn around, this one is the 00:02:10
the North. I did the same with the other magnets. You can see the North that attracts the South 00:02:21
Pole and you can see the South that attracts the South Pole. If I have two South Poles 00:02:30
on the top and the North Poles on the bottom and I try to join them, they repel. But if 00:02:42
If I turn around one of them and put the south face down and the other south is on the top 00:02:52
and I just try to join them, they join on their own. 00:03:03
They attract to each other. 00:03:08
Ok, here is this planation. 00:03:12
Here we have a magnet, a big magnet, ok, it's the same shape that the others, it's round. 00:03:14
And as we said, here is the north pole, for example, and on the bottom is the south, ok? 00:03:22
In this part is the south. 00:03:27
That means that there is like a line, and this part is north and this part is south. 00:03:30
If we have another magnet, and we divide it, and here we have the north, and here we have 00:03:41
the south so that means this part is north this one is south that means that 00:03:52
they will repel each other okay but if we put one of them face down that 00:03:59
means that this one is the south this one is the north so here is the south 00:04:15
and here is the North. South and North will attract and North and South will attract 00:04:24
so they will join because opposites attract each other. Okay so here is the 00:04:33
explanation. I hope you understood. Ask me any question you have about this. I think 00:04:46
it's fun sergio elena thank you for your question because it's very interesting uh what you asked me 00:04:53
okay so i hope uh all of you understood and have a lovely lovely day bye bye 00:05:00
