Exploring Materials - Ferrofluid (NanoDays 08, 09, 10, 11, 14)

"Exploring Materials - Ferrofluid" is a hands-on activity demonstrating that a material can act differently when it's nanometer-sized. Visitors investigate the properties of ferrofluid and magnetic black sand, learning that the surprising difference in the behavior of these two materials is due to size.

Magnetism and Nanotechnology (Middle and High School curriculum lesson)

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.

Science Xplained: Fun Ferrofluids video

Liquids that respond to a magnet? This is not science fiction, but science fact. In this segment, Dr. Ainissa Ramirez, shows the wonderful world of ferrofluids, which are iron particles floating in a liquid. When a magnet is nearby, the ferrofluid makes weird shapes and increases in viscosity. Dr. Ramirez also demonstrates how you can make a ferrofluid at home using breakfast cereal.
