In this work, the effect of electromagnetic field on natural fluid flow within the absorbent tube in the parabolic solar collector was numerical investigated. Where a solar collector with parabolic reflector was used. Water was used in the first and the flow was free as the results showed high efficiency of the device. Then a magnetic iron oxide (Fe 3 O 4 ) nanoparticle was added to make the fluid subject to influence in the electromagnetic field, where three concentrations (0.9%, 0.5%, and
more » ... ) were used to study the effect of magnetic flux on each concentration and to make a comparison. The results showed a slight effect of the electromagnetic field in the case of water use, as the efficiency of the solar collector improved by (8.8%) in the case of using the concentration (0.9%) and an electromagnetic overflow (7970 Gauss).
