In her works dated 2001-4, Sachiko Kodama gracefully utilizes the properties of ferrofluids (magnetic liquids) in order to create dynamic object forms, and in some cases interaction. Using sculpturally integrated electro-magnets, ferrofluid is manipulated to writhe and work against gravity according to Kodama's choreography. Much of the beauty of the work relies upon the natural properties of the magnetic fluid. The corrugation in the form of spikes and cones along the surface is due to the instability of the magnetic field in the medium, known as normal-field instability.
