Visitors interact with ferrofluid, a liquid that becomes strongly magnetized when in the presence of a magnetic field, in a variety of fun ways with this exhibit.
The exhibit has two places for exploring ferrofluid. In the main cylinder, individual electro-magnets placed under metal objects allow visitors to magnetize those objects and explore how the ferrofluid climbs, descends, and makes interesting shapes. In the center of the cylinder, a dual upper and lower electro-magnet system gives the visitor the opportunity to find the balance between upper and lower magnetic fields creating a string of ferrofluid between the two.
In addition, the exhibit has a fully-sealed sphere where visitors can use magnetic wands to make the ferrofluid climb the walls, drop from the top, and watch it fall through the suspension fluid.
