good morning class let's go to your natural science book okay and let's carry on with unit 6
00:00:00
in this unit remember we have been talking about magnetism yes and how can we identify
00:00:10
metallic and non-metallic devices, okay? So, in our first... in the first page...
00:00:21
In the first page, remember we talked about permanent magnets, okay?
00:00:34
That are permanent and can be man-made. Induced magnet or temporary magnets, okay?
00:00:43
that give a magnetic force for a period of time or natural magnets okay like the
00:00:50
magnet it remember we copy this in your book and you choose different examples
00:00:56
to copy in your notebook right we talked about the magnetic force the other day
00:01:03
what was a magnetic field okay although it is invisible no this area is where
00:01:10
the magnetic force work and today we are going to talk about the poles okay the magnetic poles of a
00:01:18
magnet okay so remember in all magnetic objects the moving charge begin and end at the magnetic
00:01:29
poles there are two poles the north pole and the south pole okay look at this photograph that i
00:01:40
have about this look ends and start okay in the north and in the south creating a
00:01:47
magnetic field okay what else we have to know about this okay so we have to know
00:02:08
that the poles
00:02:18
are where the magnetics
00:02:20
are.
00:02:22
If you put any two magnets
00:02:23
together, there are two things
00:02:26
that can happen.
00:02:28
One, each pole is attracted
00:02:29
to a pole with the opposite charge.
00:02:32
The magnets come together
00:02:35
because the opposite poles
00:02:36
attract each other.
00:02:38
Two, the magnets
00:02:40
push each other away
00:02:42
because identical poles
00:02:43
repel each other.
00:02:46
okay so positive negative are going to attract negative positive are going to
00:02:48
attract when the magnets are the same pose they are going to repel look at
00:02:55
this sad face okay if you put any two magnet
00:03:01
north north will repel south south will repel and the magnetic field
00:03:05
which is going to go away let's see we have learned that magnets can be
00:03:11
temporary or permanent but how can we distinguish a true magnet from a
00:03:20
magnetic material how can we distinguish a true magnet from a magnetic material
00:03:25
okay we have to see if the magnets attract to another one okay if it
00:03:33
doesn't magnet okay this mean is not a magnet itself gold and silver for
00:03:39
example are not not magnetic
