Hello everyone! Today we are going to do an experiment.

2
00:00:04,179 --> 00:00:11,179
For this we will need a magnet, a needle and a match.

3
00:00:11,179 --> 00:00:18,179
As you see, the magnet and the needle have magnetins, that is to say, they attract.

4
00:00:18,179 --> 00:00:27,179
But if we burn the tip of the needle, the magnetins that they had disappear.

5
00:00:27,179 --> 00:00:36,020
That is, it no longer has magnetism with the magnet because the structure and placement of electrons are altered.
