Magnetic liquids are taking off, Hayley Bennett reports, but not as their inventor once imagined. Through the process of thermomagnetic convection, ferrofluid is also used. Ferrofluid has actually been around since the 1960's. This is because the ferrofluids can remove heat from the voice coil and reduce the movement of the cone, as ferrofluids become less magnetic as the temperature rises. So they are all molecular fluids. We all know ferrofluid as the stuff that moves around and makes incredible geometric shapes, but what exactly is it and how does it work?

How ferrofluids work - QMAG Ferrofluid - Wikipedia UCSB Science Line Through the process of thermomagnetic convection, ferrofluid is also used in some speaker systems to reduce heat. However, the molecules on the surface are only pulled on by molecules around and below (but not above) them, leading to a breach in the equilibrium and causing the water to be pulled in the direction of the rest of the water (hence the curved water surface exhibited in the above diagram). This gets even cooler when sculptures are created (as in the top picture) by using shaped bases and manipulating the shape of the magnetic field. Colorful Ferrofluid in a Bottle is available in gold and blue. The ligand also has an attraction to the carrier fluid and kind of pulls the carrier fluid with the nanoparticles as they feel the magnetic force act upon them. www.FunExhibits.com Ferrofluid is an assemblage of magnetic particles engineered at the nanoscale, 100 times smaller than the wavelength visible light.
