ferrofluid

"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...

Transmission Electron Microscope image of nanoparticles of ferrofluid. • SIZE: The nanoparticles in the image are about 15-20 nanometers across. Scale bar representes 20 nm. • IMAGING TOOL: Transmission Electron Microscope (TEM)

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...

This is a recording of a NISE Network online brown-bag conversation held in 2014 and focuses on the applications and scientific background behind the following NanoDays 2014 kit activities: Exploring Materials - Oobleck and Exploring Materials - Ferrofluid Presented by:...

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...

The Ferrofluid Magnetoscope, by Michael Flynn, is an exhibit component that allows cooperatively-interactive control of a levitating liquid sculpture using a pair of magnet positioning handwheels. Visitors explore the properties of ferrofluid and learn about nanoscale science. It is available...
