In this paper, the effect of magnetic field on the synthesis of iron oxide nanoparticles, copper ferrite and iron oxide modified carboxymethyl cellulose nanocomposites has been investigated by co-precipitation method and the interaction of the external field with the reaction is described. In the first instance, the salts were mixed in distilled water and then, under identical conditions, the solutions were equally placed in the laboratory's usual conditions and in the presence of a magnetic field of 0.6T. At this stage, the reaction medium was changed by adding sodium hydroxide or ammonia to alkaline state, and the samples were prepared. At the end of the structural investigations and identification of the compounds prepared using X-ray diffraction (XRD), infrared spectroscopy (FT-IR) and vibrating sample magnetometer (VSM). The average particle size was measured using the width of the X-ray diffraction patterns and the shear relation, as well as the scanning electron microscopy (SEM). The results showed that the synthesized samples in the presence of external magnetic field improved the crystallinity and reduced the size of the nanoparticles by maintaining the crystalline structure. Also, CMC saturated iron oxide saturation magnetization increased significantly, which improved the magnetic properties of this nanocomposite. Magnetic nanoparticles are used in magnetic recording, medical applications, ferrofluid used in loudspeakers, a magnetic hyperthermic method that is a therapeutic method for cancer that produces heat in the stomach, leading to tumor loss.
