1 00:00:02,930 --> 00:00:14,750 Okay, here we have one magnet and when we put the other magnet with the South Pole in 2 00:00:14,750 --> 00:00:24,289 front of the other South Pole, as you can see, if we just try to join them, side 1 turns. 3 00:00:24,289 --> 00:00:30,789 Because South Pole and South Pole repel each other, okay? 4 00:00:30,789 --> 00:00:35,729 And North Pole and South Pole try to join, they attract each other. 5 00:00:35,729 --> 00:00:38,590 Okay, so here is the picture. 6 00:00:38,590 --> 00:00:45,390 We have the magnets, South Pole in front of South Pole, we cover it as we did yesterday 7 00:00:45,390 --> 00:00:52,289 with a paper, and we spread the iron fins. 8 00:00:52,289 --> 00:01:03,600 to see the magnetic field. Here is one magnet and you can see and here is the other one. 9 00:01:03,600 --> 00:01:15,859 Let's see the lines of the magnetic field. Here we have the ones in the same one as yesterday 10 00:01:15,859 --> 00:01:31,060 from the south pole to the north pole, in both sizes, here we have the same, but what 11 00:01:31,060 --> 00:01:35,640 happens between the two magnets? 12 00:01:35,640 --> 00:01:59,200 I have to do it very carefully, because I want you to see it, ah, we have it, ok, as 13 00:01:59,200 --> 00:02:05,219 As you know, they repel each other, so the lines try not to touch. 14 00:02:05,219 --> 00:02:15,419 The lines of this magnet go just avoiding to touch these lines, so they just go and 15 00:02:15,419 --> 00:02:19,139 open to not touch. 16 00:02:19,139 --> 00:02:23,139 This is one of them. 17 00:02:23,139 --> 00:02:30,439 Now let's see what happens when we put the South Pole in front of the North Pole. 18 00:02:30,439 --> 00:02:40,840 covered with a piece of paper you can see one of the magnets it's here the 19 00:02:40,840 --> 00:02:51,759 other one is here both have their lines of the magnetic field as you know but 20 00:02:51,759 --> 00:02:58,759 what happens between them what happens with the lines of the magnetic fields of 21 00:02:58,759 --> 00:03:04,620 these two magnets with the South Pole and the North Pole in front of each 22 00:03:04,620 --> 00:03:20,680 other. Let's see, just very carefully. 23 00:03:20,939 --> 00:03:30,199 Can you see this? The lines go from the South Pole to the North Pole 24 00:03:30,199 --> 00:03:36,960 because they are attracted. As happens here, from North to South, here we have 25 00:03:36,960 --> 00:03:43,680 from south to north and the lines just join. Isn't it incredible and beautiful? 26 00:03:43,680 --> 00:03:52,520 So this is an experiment. Isn't it beautiful? I'm sad we couldn't do this in 27 00:03:52,520 --> 00:04:02,439 the class because when you watch it, it's more beautiful. But it's what we have. So 28 00:04:02,439 --> 00:04:10,199 now it's time you go to your folder open the document of the magnetic field and 29 00:04:10,199 --> 00:04:18,920 fulfill the two last boxes you have to write the results and then you have to 30 00:04:18,920 --> 00:04:26,100 write the conclusions please remember when you have South Pole with South Pole 31 00:04:26,100 --> 00:04:32,279 together and when we have the South Pole with the North Pole okay I hope you 32 00:04:32,279 --> 00:04:39,860 enjoy it and you like it so see you tomorrow bye bye
