Ferromagnetic Fluid at OMSI

Ferromagnetic Fluid at OMSI, originally uploaded by JoshB.

We took our Webelos to OMSI (the Oregon Museum of Science and Industry) a few weeks ago. There were some cool things in the Physics lab.

This is some ferromagnetic fluid – think iron filings suspended in liquid. They move and react to magnetic fields, like this one, with me moving a small magnet underneath the plexiglass container. You have to see it in motion to really appreciate how weird and cool it is.
