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...

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...

they have smaller voice coils, which limit their overall power output. Ferrofluid is a suspension of very small (typically 10 nm) iron oxide magnetic particles...

rely on the general principle of ferrofluids - fluids that display magnetic attraction. Following research on ferrofluids during the 1960s, the ferrofluidic...

heating-cooling cycles to clear. In 2015, a new design was introduced that uses ferrofluid in place of wax. British entrepreneur Edward Craven Walker had the idea...

However, when working with ferrofluids, the fluid effects of wetting and evaporation should be considered. The ferrofluid’s movement and evaporation rate...

many possible control-based applications. MR fluid is different from a ferrofluid which has smaller particles. MR fluid particles are primarily on the micrometre-scale...

curvature. Bimorph mirrors are rarely made with more than 100 electrodes. Ferrofluid concept mirrors are liquid deformable mirrors made with a suspension of...

convection can occur when an external magnetic field is imposed on a ferrofluid with varying magnetic susceptibility. In the presence of a temperature...

together with a ruler can be used to measure the poles per inch of a magnet. Ferrofluid Magna Doodle Vincent A. Ardizzone (January 14, 2004). "VIEWING FILM FOR...
