Electric current though liquid - Magnet interaction I f a have a coil with an electric current flowing through it, and I place it inside of a magnetic field, it will move.
Now my question is, what happens if I have a droplet of liquid with an electric current flowing through it, will it also move ? If not, why not ?
 A: Yes, of course it will move.  Here is a familiar science demonstration, the
mercury 'beating heart'  BEATING HEART  which
shows a crude battery circuit (the mercury and the iron in a
mild acid).   When the iron touches the mercury, the battery
puts a current through the contact point, and that current
deforms the mercury because it creates a changing magnetic field.
The deformation breaks the contact, and the force on the mercury
goes away, which reestablishes electric contact... and it oscillates.
It's literally a changing magnetic field that's moving the mercury,
but the coil-in-a-field causes more of a torque effect than
a translational motion.   The application of torque to a liquid
is a difficult thing to demonstrate; how would one know that
a liquid drop was rotating?
A drop of conductive liquid in a changing magnetic field WILL transformer-couple
to that field, and generate a little loop of internal current.
The problem, then, is to see a drop become nonspherical when
a changing magnetic field excites it, and then see some indication
of axial tilt due to a nonchanging magnetic field.  
Probably, this could be accomplished, with stop-action video
to record droplets in free fall.  It'll look like a bunch
of wires with a quivering raindrop falling through a magnet gap...
