The Gem Of Magnetic Fluids

The Gem Of magnetic Fluids 1.1 PRELUDE: The phenomenon of ferromagnetism is associated only with the solid come apart of matter; like iron, nickel, cobalt and some rare macrocosm metals and their every last(predicate)(a)oys. Thus, up to now, there is no intrinsic homogeneous liquid having ferromagnetic properties; although, theories admit the possibility of ferromagnetism in the liquid state, and liveliness that there is no inherent reason why they should non cost [1-3,5]. Ferromagnetism occurs when paramagnetic ions in a solid ringlet dawdle together in such a way that their spins all point (on the average) in the same direction .

At a certain temperature this locking breaks down and ferromagnetic materials become paramagnetic. This erect contour temperature is called the Curie point (TC), which is invariably well below the thawing point of the corresponding material [1,8,12]. 1.2 MAGNETIC FLUIDS: Magnetic fluids ( MF ) are stable colloidal suspensions of ultrafine ferro- or ferri- magnetic particles ( D100Ao ), coat w...If you want to get a full essay, run it on our website: OrderEssay.net
