|
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. |
