Incredible short film by Kim Pimmel. I won't pretend to understand the science behind it but I can tell you that this is 100% real and is shot with a macro lens.
From the artist:
"I combined everyday soap bubbles with exotic ferrofluid liquid to create an eerie tale, using macro lenses and time lapse techniques. Black ferrofluid and dye race through bubble structures, drawn through by the invisible forces of capillary action and magnetism"
Time-lapse sequences: Nikon D90, Nikkor 60mm macro lens and custom built intervalometer.
Motion-control: Arduino driven scanner platform and mirror rigs
Score: Ableton Live
