are there any already existing devices on the market or possible ways in which one can make a liquid metal slip contact like a mercury contact in which the mercury can be held at a specific location within a confined space with the help of magnetic field?
I know that mercury itself is very weak or for all practical purposes non-magnetic and only responds to B fields if a current runs through it but are there any other ways to make a reliable connection by holding the mercury at a particular place given that it would be subject to rotation?
imagine the mercury inside a torus shaped tube and as the tube rotates the mercury should ideally be held at a particular place in the tube against the forces of friction from the inner surfaces of the rotating tube and also against gravity, is this doable?thank you.
