Retake For OC

Do you have the same results spinning the other way?

the music is a nice touch !!!!!!!!!

Thanx ;)

So, you get an extra gram or so at higher RPMs. Is it aerodynamic? Or is it artificial gravity? ;^)

Thanks for taking the time to do redo the experiment with significant space between the WhipMag and scale, greatly reducing the probability that the spinning magnets are affecting the circuits in the scale.

I think there may be a slight downward pressure caused by aerodynamics on the slotted rotor. Theoretically, for the shown rotational acceleration, torque would be applied on the vertical axis in the upward direction. This is an imaginary vector put in this dimension for mathematical reasons and this demonstration helps to prove that.

I used the enclosed rotor which by design should have a small lift because of the turbulance generated by the screw heads. As shown it is insignificant, if any. ;)
