A survey of ferromagnetic liquid applications
Abstract
Ferromagnetic liquids, also called 'ferrofluids' are colloidal suspensions of submicron-size single domain particles in a carrier liquid such as hydrocarbon, fluorocarbon or water. Ferrofluid responds to a nonuniform magnetic field by collecting in regions where the magnetic field is most intense. The present paper contains a brief review of certain applications which have been proposed for magnetic liquids. Primary emphasis is placed on some of the more well known devices, such as dynamic feed-through seals, bearings and lubrication, and energy conversion systems. Medical applications of ferrofluids are also discussed. Sketches and references, rather than detailed mathematical models, are presented to give the reader a qualitative appreciation of the various applications.
