ferrofluid

[′fe·rō‚flü·əd]
(materials)
A colloidal suspension of ultramicroscopic magnetic particles in a carrier liquid, used as a lubricant or damping liquid.
(physical chemistry)
A colloidal suspension that becomes magnetized in a magnetic field because of a disperse phase consisting of ferromagnetic or ferrimagnetic particles.
