We began to research Ferrofluid and learned many things. In many languages Fer means iron, and Fe represents iron on the periodic table of elements. The fluid, which in this case was vegetable oil, describes the suspension that the magnetic shavings (found in the toner we used) are in. We decided to explore Ferrofluid for our Science Fair project. We did many experiments to discover what happens to the Ferrofluid when a variety of magnet sizes and strengths were introduced. We attempted to replicate experiments we had seen where the fluid responds to magnets and peaks in really amazing ways. At first, we were disappointed with our results. We didn't get the reactions that we had seen on the videos. But then we realized that the videos probably showed perfected experiments, and we were just starting to learn about mixing the toner and oil, playing with the right volumes and ratios. We mainly saw bumps and small spikes, but realized that even though there weren't huge results, they were pretty interesting anyway. We also explored real life applications for this amazing (and very cool) substance! Some of the most interesting applications, that everyday people might be familiar with, are: Speakers; inside the speakers there are wires that can overheat from frequent movement. The Ferrofluid surrounding the wires keeps them cool so the speaker will not overheat. Another amazing thing we found is that a man created a prototype for an artificial heart. He used the Ferrofulid to control the pulmonary value by the ferrofluid moving between two electromagnets to create the open and close mechanism for the valve. We are really looking forward to sharing our findings with all of you.
