The magnetic field of the windings need to be a little stronger but the concept seems to be working.  The idea is to have ferrofluid dancing around from a simple PCB. This is obviously just a concept but with more windings and perhaps with a core in the middle of these printed windings, it can be possible. (Also, I need to find a way not to stain the container with the ferrofluid .. its a little messy)

Since this does not actually have to do with the Linear PCB motor (although same pcb), I have set up a different project page for this:
