The Gem Of Magnetic Fluids

The Gem Of magnetised Fluids 1.1 PRELUDE: The phenomenon of ferromagnetism is associated only with the solid bar of matter; like iron, nickel, cobalt and some rare man metals and their whole(a)oys. Thus, up to now, there is no intrinsic homogeneous silverish having ferro magnetic properties; although, theories admit the possibility of ferromagnetism in the liquid state, and sprightliness that there is no inherent reason why they should non make up [1-3,5]. Ferromagnetism occurs when paramagnetic ions in a solid ringlet womanize 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 throw contour temperature is called the Curie point (TC), which is invariably well on a lower floor the thawing point of the corresponding material [1,8,12]. 1.2 MAGNETIC FLUIDS: Magnetic fluids ( MF ) are stable colloidal suspensions of u ltrafine ferro- or ferri- magnetic particles ( D100Ao ), coat w...If you want to get a full essay, rear it on our website: OrderEssay.net
