Ferrofluid Demonstration

 

This demonstration is a product of Nanodays and NISE Network (Nisenet.org). Included in your demonstration kit is a guide with directions and information on how nanotechnology is involved.

 

 

 

In this demonstration you have a vial of black sand, a vial of black sand and ferrofluid, and a magnet.

 

Hold the magnet next to the vial of black sand. How does the sand react?

 

Now try the same thing with the vial of ferrofluid. Use the magnet to drag the sand up the side of the vial.

 

Does the ferrofluid act the same way the black sand does?

 

Try removing the magnet. What happens?

What's going on? Check the guide here.
