Effect of Nano- particles on the MagneticField Induction for Iron FillingsCrushed for Different Crushing Times

Abstract

Three different coils (100, 150 and 200 turns) were prepared using U-shape test tubes and raw material of iron was brought from Sudan minster of miner and meteorology (Fe2O3 purity 80 % investigated in chemicallaboratory). The samples were crushed four different intervals of times (2, 6 and 10 minute), the samples placed in magnetic field induction through the different coils and the relation between current I and magnetic field induction four different times of crush was investigated.
