Could someone please comment on this video?

I have searched the OU site, but found very little.

Cheers

Hi,

All the rotation comes from his hand holding the ring shaped line of magnets...
You can see this best at 05:31 when everything is relatively at standstill: no hand movements for some seconds while the 'rotor' is in the upright stationary state. Then the rotor loses its balance and gravity starts it slowly rotating in the unbalanced state.

I tried building one with no success. The only major difference is that the central magnet in mine wasn't mounted on a ball bearing. I would like to see video of it moving without a person holding the outer ring. It's quite easy to feed energy into these kind of things (wittingly or unwittingly) with a slight move of the hands. Although he says the central magnet is just a speaker magnet, it looks like something more to me with that segmented appearance.

The segmented magnet seems to be a multipole disk magnet (each segment next to the other is a different pole, NSNSNSNS)  usually such magnets are not used in speakers but in floppy drives motors.
I am sure when the hand is replaced by a fixed holder, the initial rotation will soon stop.

There is no vortex (there cannot be) in those magnets in their ring like setup, only handmovement gives some light pushes to the segmented 'rotor' magnet.

In tha past I tried it with a round magnetic ball instead of a ball bearing and it does indeed spin.

First this motor is called Hamel motor, and this not work!

What make the rotor spin? The hand of the person that hold the magnet, with a fixed rotor, nothing will move unfortunitly.
