Something different. How about this.....

The idea was nice... but didn't worked as i expected  >:( the steel ball i got was too light... it was 15mm diameter... an probably the bicycle wheel was too heavy, and not well balanced.

I had to buy a neodimium block 20x20x20 too because i had no magnets here to play...

Thinking about the torque

T=F x r *sin(teta)

And F=M*G


....

I don't know if the video is false, since the ball should be attracted in the direction of the magnet and than stops there it shouldn't spin further... maybe thats why he didn't let it run for too long... I mean the magnet will attract the all points of the sphere it will find equilibrium... i guess

What you think about?

Steve:
Hmmm, finding its equilibrium might be true....
Not sure, however.

Steve:
It seems even to accelerate in the beginning...

This is the book the guy mentioned at the start....

I watched it very close...

the sin of 20° is 0,34

so the torque the ball should cause to turn the wheel is the mass of the ball times G times 0,34 times the radius of the wheel...

the problem i see is that the moment of inertial of the ball is much smaller than the rotor... thus the transference of rotation is really poor...

sebosfato:
Maybe the wheel should not touch the external radius of the sphere... this way it can be out of equilibrium.... i guess... i'm building  new one with two children bicycle wheels =)

It will look just like the one in the video, except that one seems made of wood probably balsa or something else light weighted,,,


notice how the ball stands close to the corner of the magnet... maybe i need a longer magnet to achieve this effect...
