This is a sequel to the SinkScience...
Series #03 with the CD Turbine and Magnetic Balls
Here I have a configuration with some magnetic balls
and I want to look at the phenomenon
of the rotation of the ball as it revolves around...
following the magnets in the CD turbine...
The magnets we can see here, by the way, by removing this cover.
You can see the six magnets and how the...
normally attracts pretty good on there.
so what I'm going to do is buffer it a bit with this spacer
plus the actual pyrex bowl
and jus t get that reset up
ok, there we go
ok, now I can see how the two little arms
with the balls on there can act as an indicator,
to let us know when things are going around or revolving or whatever
ok, let's fire it up...here we go...
that's pretty cool...
You can see how the ball is rotating
at the same time taht it is revolving.
here' a little more throttle pressure here
I'm going to shut it down...things are getting too violent here
You can see the two arms have joined together on the ball there
It still does the same basic rotational thing
As it's revolving, it rotates
Very interesting phenomenon!
okay,
i'm welcoming theories on that one!
Ok, another SinkScience video here.
The Balll In a Bowl. This is a magnetic ball insude
of a bowl, which is on top of the CD turbine.
As you can see underneath this cover...
has magnets which rotate when I turn on the
control valve here. The rotational effect
coming from the water supply from the tap.
I'll put the cover on there,
Put the pyrex bowl on top, there's the magnet inside the pyrex bowl on top
I put a saran-wrap cover over the bowl as well.
to try and contain the ball this time around
because i don't wnat any broken windows or busted teeth, so
Ok, we are ready to go, I'm going to turn on the turbine
and we willl see the effect on the ball
as it goes around...
everything is relatively normal/ This effect is very strange, however
I would not exactly call it normal.
This is like a continuation of the previous attempt with the six ballls
in SinkScience #03 video
ok, that's one interesting effect.
I'm going to increase the water pressure now
to increase the RPM's of the machine
Now I'm going to increase the speed a little more.
ahhh,
the ball moves backwards. That's very interesting! The ball...
has reversed direction. it's going counter to the direction
of the rotation of the turbine
at pretty much the same speed as it was going
in the same direction of the turbine. Ok, now I will slow down the turbine and see what happens
The radius is tightening down on the...
ball there...
I turning down the turbine a little bit more.
The turbine is going slower and the ball is going faster; interesting phenomenon.
turn it down a little more
a little more
okay, now we have...
the ball is still rotating counter to the direction...
of the turbine.
The turbine is running at a hundred or two hundred RPM,
now I'll turn it right down and see what happens here...
The ball slows...
now it's rotating with the magnetic field of the turbine.
As I turn it down even more
there you can see the actual rotation if the turbine.
It's interesting to note, if you look very carefully
it's very obvious to me, the ball is rotating...
as it revolves around
it's rotating quite extremely. it' similar to
the way the Earth would be rotating as it revolves around
the sun. I wonder if it isn't a similar phenomenon.
Ok, so I welcome suggestions on this.
Ok, so I welcome suggestions on this.
You can see as I increase the throttle
and water pressure and increase the RPM's of the turbine,
the ball continues to rotate
in this peculiar cyclic oscillation.
It seems to have three lobes to the sides of the arcs
as it goes around
I'll increase the speed of the turbine
a little more...
and finally a little more...
chaos, and then...
suddenly, the ball wants to go backwards!!
the ball is...
most natural running backwards to the rotation of the turbine,
which is a very strange phenomenon,
and gives me lots of ideas...
for different types of motors.
