Nice analysis but we already know the hourglass shape of the dielectric magnetic field thus the inner surfaces of the two toroidal back to back 3D geometry magnetic field.

Mike's ferroliquid shows only the inner part of the ejected magnetic field generated on the domain wall through the poles but it does not show the curling of the field lines returning through the poles forming the two torus back to back effect.

I think the explanation the large mass of ferroliquid not showing the curling of the flux is liquid pressure inside the container and buoyancy not allowing the ferrofluid to move freely and follow the magnetic flux of the field.

Ferroliquid aquarium may definitely produce a 3D projection of the field but it can not show the entire field since it lacks the sensitivity in doing so.
