Moving a thread with embedded ferromagnetic pieces about it's length can be moved by varying the magnetic field strength and direction. In the crudest sense, this is similar to a catheter that is magnetically controlled through blood vessels to treat various circulatory disorders.

A ferromagnetic tip is placed on this thread as it is buoyed to a piece of foam within the mineral oil. It strikes the glass like a snake as a magnetic field is applied.
