The Gem Of Magnetic Fluids 1.1 PRELUDE: The phenomenon of ferromagnetism is associated only with the solid majority rule of matter; like iron, nickel, cobalt and some rare fault 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 touch that there is no inherent reason why they should not exist [1-3,5]. Ferromagnetism occurs when paramagnetic ions in a solid bolt of lightning to pee-peeher in such a way that their spins exclusively point (on the average) in the same direction .
At a certain temperature this locking breaks down and ferromagnetic materials become paramagnetic. This rhythmic pattern temperature is called the Curie point (TC), which is invariably well below the melting 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:
