Nanoenhanced oil recovery has emerged as a promising method for improving and enhancing oil recovery. However, nanoparticles face the challenge of clumping together under reservoir conditions, hindering their movement through the porous medium and interaction with the oil/water interface. To fully understand the impact of different nanoparticles and electromagnetic fields on phase transitions and oil recovery, it is crucial to consider the complex interactions involved. These interactions can be influenced by factors such as nanoparticle concentration, size distribution, surface chemistry, and base fluid properties. In this study, a core-flooding experiment was conducted to evaluate the effectiveness of synthesized nanoparticles (BaTiO

FTIR analysis confirmed the presence of functional groups and mineral composition. XRD analysis examined the crystal structure of the materials, while XPS, capacitance, and resistance measurements determined the elemental composition, chemical state, and electronic state of the materials. These analyses aimed to investigate the influence of an electromagnet on fluid mobility. Electromagnetic fields improve the dispersion and stability of nanoparticles in the reservoir, preventing aggregation and maintaining the effectiveness of nanofluids. Enhance the viscosity and mobility of the injected fluids, leading to better sweep efficiency and displacement of oil. The core-flooding experiment allowed us to determine the recovery factor. The results demonstrated that BaTiO
