Okay, here we have one magnet and when we put the other magnet with the South Pole in 00:00:02
front of the other South Pole, as you can see, if we just try to join them, side 1 turns. 00:00:14
Because South Pole and South Pole repel each other, okay? 00:00:24
And North Pole and South Pole try to join, they attract each other. 00:00:30
Okay, so here is the picture. 00:00:35
We have the magnets, South Pole in front of South Pole, we cover it as we did yesterday 00:00:38
with a paper, and we spread the iron fins. 00:00:45
to see the magnetic field. Here is one magnet and you can see and here is the other one. 00:00:52
Let's see the lines of the magnetic field. Here we have the ones in the same one as yesterday 00:01:03
from the south pole to the north pole, in both sizes, here we have the same, but what 00:01:15
happens between the two magnets? 00:01:31
I have to do it very carefully, because I want you to see it, ah, we have it, ok, as 00:01:35
As you know, they repel each other, so the lines try not to touch. 00:01:59
The lines of this magnet go just avoiding to touch these lines, so they just go and 00:02:05
open to not touch. 00:02:15
This is one of them. 00:02:19
Now let's see what happens when we put the South Pole in front of the North Pole. 00:02:23
covered with a piece of paper you can see one of the magnets it's here the 00:02:30
other one is here both have their lines of the magnetic field as you know but 00:02:40
what happens between them what happens with the lines of the magnetic fields of 00:02:51
these two magnets with the South Pole and the North Pole in front of each 00:02:58
other. Let's see, just very carefully. 00:03:04
Can you see this? The lines go from the South Pole to the North Pole 00:03:20
because they are attracted. As happens here, from North to South, here we have 00:03:30
from south to north and the lines just join. Isn't it incredible and beautiful? 00:03:36
So this is an experiment. Isn't it beautiful? I'm sad we couldn't do this in 00:03:43
the class because when you watch it, it's more beautiful. But it's what we have. So 00:03:52
now it's time you go to your folder open the document of the magnetic field and 00:04:02
fulfill the two last boxes you have to write the results and then you have to 00:04:10
write the conclusions please remember when you have South Pole with South Pole 00:04:18
together and when we have the South Pole with the North Pole okay I hope you 00:04:26
enjoy it and you like it so see you tomorrow bye bye 00:04:32
