Homopolar motor rotation in Vacuum

[StoyanNikolov]

Hi again,
I've found interesting video.
Roller homopolar motor :
Roller Motor
Do you think the motor from 1:08 min Will self rotate in Vacuum/Space
(No other forces : Gravitational or Other type.)
Thank you in advance.

I see no reason why it wouldn't rotate in a vacuum, why do you think it wouldn't?

Thank you for the Reply. 

How much you are confident it will self rotate?

I've asked this topic in other forums and the opinions were not 

so confident.

I am fairly confident it will spin in a vacuum because the spinning is self-referential, that is, it does not spin with reference to anything other than itself.

Some people may confuse rolling with spinning. Of course, it cannot roll in a vacuum as that requires an external surface to roll on.

I think you're correct, I think the wire would tend to rotate instead of the battery though.

I am pretty much 100% confident that wire would rotate around the battery but the battery is heavier than the wire I would think.

I agree, it will rotate in the vacuum of space however without touching a object it will not have the friction force that causes to roll.
