Magnetism and Nanotechnology: Exploring Ferrofluids
The lesson has students expand what they know about magnetism through study of a liquid magnetic material called a ferrofluid. Ferrofluid is a unique material that has both magnetic and liquid properties. It is a colloidal solution of nano-sized particle of magnetite suspended in a liquid. (Purchased). This activity will review what students know about magnetism and compares that knowledge to how ferrofluid behaves.
