Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...
Ferrofluidic is the brand name of a staged magnetic liquid rotary sealing mechanism made by the Ferrotec Corporation. Ferrofluidic seals, also known as magnetic liquid rotary seals, are employed in various rotating equipment to facilitate rotary motion while ensuring a hermetic seal.
A ferrofluid mirror is a type of deformable mirror with a reflective liquid surface, commonly used in adaptive optics. It is made of ferrofluid and magnetic iron particles in ethylene glycol, the basis of automotive antifreeze. [1] The ferrofluid mirror changes shape instantly when a magnetic field is applied.
Ferrofluid is a suspension of very small (typically 10 nm) iron oxide magnetic particles in a very low volatility liquid, typically a synthetic oil. A wide range of viscosity and magnetic density variants allow designers to add damping, cooling, or both. Ferrofluid also aids in centering the voice coil in the magnetic gap, reducing distortion.
Sachiko Kodama (born 1970) is a Japanese artist. She is best known for her artwork using ferrofluid, a dark colloidal suspension of magnetic nano-particles dispersed in solution which remains strongly magnetic in its fluid. [1]
In this week's episode of Experimental, learn how to make magnetic ferrofluid dance unlike any other liquid!
Ferreira designed and tested a method to remove microplastics from water, following what he described as thousands of failed attempts. Ferreira has stated that he was inspired by an article by Fermilab physicist Arden Warner, who developed a new approach to cleaning up oil spills, using magnetic principles, [10] and made a device that uses a magnet-based method to remove the particles from ...
At least nine people were injured Monday after a Delta Air Lines plane was involved in a crash upon landing at Toronto Pearson International Airport, officials said.
