Question about rotating structures

That is accomplished one of a few ways.
1. Conductive rings meet each other at the point of rotation, in direct contact
2. A ring on one side, and brushes on the other the drag around the ring keeping
contact (used in old generators and amusement part rides)
3. Same concept as rings, but using induction so there is no physical contact
