Future of Electrotechnics: Ferrofluids

Advances in Electrical and Electronic Engineering, 2008
Magnetic liquids enabled development of new devices and technologies that are a useful alternative to theexisting ones. Many of these applications are still in progress and do not represent any break-through discoveries yet.Nevertheless one may expect that owing to their remarkable qualities magnetic fluids will become in the future a part oforiginal ...

Ferrofluid separator for nonferrous scrap separation [PDF]

, 1974
Behavior of nonmagnetic objects within separator is essentially function of density, and independent of size or shape of objects. Results show close agreement between density of object and apparent density of ferrofluid required to float it. Results also
