Comprised of nano-scale magnetic particles. Yes, please fill out our contact form with the subject "Wholesale", please include the display you are interested in and we will send you a price sheet. Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of a magnetic field. We use professionally made FerroTec EFH1 series ferrofluid. If you have an idea for a display and need some help, shoot us an email on the contact page. The suspension liquids are not retail products and are not easy to use. A ferrofluid (portmanteau of ferromagnetic, and fluid) is a liquid which becomes strongly magnetized in the presence of a magnetic field. This minimizes R&D for the project and preserves our trade secrets. The easiest way for us to collaborate with creators, is to install ferrofluid in a chamber and then ship to the creator to design around. We have a number of different suspension liquids we use to prevent ferrofluid from staining. When exposed to a magnetic field, the nanoparticles form regular. + Why does ferrofluid spike?Ī ferrofluid forms spikes along the magnetic field lines when the magnetic surface force exceeds the stabilizing effects of fluid weight and surface tension + What is the best suspension for ferrofluid? Ferrofluid is a colloidal liquid made of particles less than 10 nanometers in diameter. Learn more about the history of ferrofluid. Papell is credited in literature with the preparation of the first magnetic fluid, based on kerosene. On the other hand, the high nanoparticle concentration and magnetization of FF2 give rise to a significant magneto. Although the array of spikes on the surface of the ferrofluid is spectacular, this property is not particularly useful. Papell envisioned converting the nonmagnetic rocket fuel into a fuel having magnetic properties so that it could be controlled under zero gravity by powerful magnets or pumped through switching magnetic fields. Thus, the ferrofluid with the high magnetization interacts with the magnetic field and exhibits stationary behavior near the transformer core due to the magnetic force keeping the ferrofluid stacked in the magnetic field gradient. The ferrofluid aligns with the magnetic field lines of the magnet to produce the spikes. The absence of gravity allowed the fuel to float in the holding tank and it was therefore a challenge to pump the fuel efficiently into the rocket engine. Steven Papell at NASA was tasked with controlling and directing liquid rocket fuel in outer space.
