Ferro Fluid – Smart Material

Product Description

Design and technology as well as science teachers are buying the amazing ferrofluid ¨C a truly magnetic liquid. This consists of micron size magnetic particles (magnetite) in a mineral oil. Particles are coated in a surfactant which prevents them clumping together. When a magnet is in close proximity the magnetic particles in the Ferrofluid take up the shape of the magnetic field ¨C a 3-D version of the classic iron fillings on a piece of paper experiment that we used to do in schools.
