The Gem Of Magnetic Fluids

The Gem Of Magnetic Fluids 1.1 PRELUDE: The phenomenon of ferromagnetism is associated only with the solid nation of matter; like iron, nickel, cobalt and some rare farming metals and their whollyoys. Thus, up to now, there is no intrinsic homogeneous touch-and-go having ferromagnetic properties; although, theories admit the possibility of ferromagnetism in the liquid state, and upraise that there is no inherent reason why they should not exist [1-3,5]. Ferromagnetism occurs when paramagnetic ions in a solid go over to reachher in such a way that their spins on the whole point (on the average) in the same direction . At a certain temperature this locking breaks down and ferromagnetic materials become paramagnetic. This pitch contour temperature is called the Curie point (TC), which is invariably well below the unfrozen 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 ( D100...If you neediness to get a full essay, order it on our website: OrderCustomPaper.com
