Developed as a liquid rocket fuel for NASA in 1963, ferrofluid is an oily black fluid that becomes magnetized in the presence of a magnetic field. The liquid itself assumes the shape of magnetic lines of force. It forms spiky peaks and valleys that reveal the invisible structure of magnetism. This program was filmed in slow-motion macro video.
