LIQUID SCULPTURES with FERROFLUID
SPIKED WITH MAGNETIC NANOPARTICLES

Ferrofluids are colloidal mixtures - magnetic nanoparticles suspended evenly throughout a carrier liquid.
When placed in a magnetic field, the suspended particles cause the entire fluid to become strongly magnetized. In these images a small drop of ferrofluid is placed within a magnetic field created by a neodymium iron-boron rare-earth magnet.
The peaks and troughs result as the magnet tries to pull the liquid along its field lines.
