Hi. This is Andrea from Beadaholique.com. In this video I thought we do something a
little different.
We're going to do a science experiment.
So I stumbled across this and I realize once I got to work that hey we
carry all of these items so this would be a fun little
experiment to do
at work.
What you're going to need for this is
you're going to need some neodymium magnets which we sell here.
This comes in a pack of three
and I'm using all three of them stacked together.
You need a AA battery.
Everybody has one or two of those
roaming around their houses I think.
Then you need some solid copper wire. Now this is important, not the copper plated
or the copper colored craft wire, the solid copper wire.
This is twenty gauge but it really doesn't matter.
You're going to build an armature and what your armature needs to do
is it needs to fit around the magnets but not snugly. There needs to be a lot of
wiggle room.
It needs to come up
and end in a point
that is roughly the size
of the battery between the point and the base.
Just a little bit longer.
This is just one of the armatures you can build but you can also build a
swirl.
I'm show you that in a minute.
Now this is called a homopolor motor
and I'm not even going to begin to explain how it works. You can look it up
online. I did and I still don't quite get it but it's really cool and it's a fun
little experiment to do.
So what I'm going to do is I'm going to put the positive end of
my battery right on
the stack of neodymium magnets.
Now a note about these magnets they are super duper strong so be careful with
them.
Always use
adult supervision when you are using these magnets and especially when you're
building a motor because you are generating power.
What you're going to do here
is you're going to take your armature
balance it right on top there
and you're going to let the magnet and the battery do it's thing.
Now this is really cool and really fun.
If the battery and magnet motor is not spinning the wire they're
still electricity being generated so be very careful. If I was to hold this still
and it was taking a connection between
the magnets and the battery
this wire would get very hot.
But other than that
this is just
so cool i think and so much fun.
I also made a swirly
armature.
This one is going to take some practice to get it right to get the
balance right.
It's going slowly
you want to make
a connection between
the battery and the magnet. That's the key and the copper.
There we go.
so this will go for quite some time. This a fun little experiment to do with
young ones like I said with supervision
or if you're just like me and you
are highly entertained stuff like this.
So once again neodymium magnets from Beadaholique.com, solid copper wire from Beadaholique.com,
battery from you junk drawer or your remote control
and you have yourself a simple motor. Thanks.
