Well, maybe from one capillary there is very little energy in practice. Or must be a lot of them.
The case with magnetic fluid is more interesting.
A year or two ago, I suggested using a variable density magnetic fluid, and I had a question.
But no one, as always, paid attention to it.  :)
Then I’ll ask again, the density of the magnetic fluid, which is higher than the level of a large bath
and which is surrounded by a ring magnet is largest than the rest magnetic liquid , isn't it?

There is an opinion  that the magnetic fluid suspended by a magnet on the right side will not push the float. Because the magnetic fluid will not have buoyant properties.  :(

If the right side cannot push the float higher, the float on the left and the right will remain at the same level, even though the level has dropped on the left.

Alternatively, as a progression of this thought, I imagine you could suck the level lower on the left with a submerged magnet. For there not to be an imbalance of force, there would have to be an increase in buoyant force on this side. I do not think that is the case. There has to be an imbalance. Surely the "ring" cannot be magnetic at all, sliding through the magnetic fields unhindered.

I wonder if the suspended iron in the ferro-fluid creates a structure within the fluid, increasing resistance to the hypothetical ring?

You can make it even easier, just use two liquids of different densities. But there will be no OU. 8)

Certainly structures of different density are created in the magnetic fluid under the influence of an external magnetic field.

it may be that the densities balance out by a factor of the height.
