You can only do this if you use pulsating DC or if not, you must change the
velocity of the liquid. Are you trying to make a generator? Picture this:
fill the liquid in a cylinder but not completely, apply the current to the
liquid and tip the cylinder so all the liquid falls toward one end then tip
it the other way, if you do this at a nice constant rate you should induce
AC in the other wire (the AC will have some EM noise to it, since you can't
get the fluid to move perfectly), hook the AC circuit to narrow band pass
filter and you should end up with a clean AC signal, the frequency depends
on how fast you move the liquid. Another thing is put the liquid in a pot
and apply DC to it, boil the liquid and you should end up with EM noise
being induced in the other wire, you will have just made a random noise
generator.

..Or maybe I'm totally wrong.
