Title: Does spin direction change dependent on hemisphere?
Post by: charli on 22/06/2021 03:29:15

Paul has a sound question:

"When I place my modern [Brand Removed] Wireless Speaker on a flat surface and play music it slowly rotates in a clockwise direction
Why?
Would it rotate counterclockwise in the northern hemisphere?"

It's not one of those archaic Leslie Speakers?

Why?

I assume the vibration from the music is causing the speaker to move.  The direction of the movement is a result of the points of contact of the speaker to the surface it is on.

No, it has nothing to do with the Coriolis effect.
