Today, many attempts have been made to introduce small particles with high thermal conductivity to the heat transfer fluids to improve the thermal properties of conventional fluids used in heat transfer. Therefore, in this paper Fe 3 O 4 nanoparticles are used as fluid additives to study properties of the laminar flow regime. So, the laboratory setup was designed to experimentally investigate the forced heat transfer in a copper spiral coil under constant heat flux. Furthermore, the effect of the alternating magnetic field on the improvement of the heat transfer rate of forced convection heat transfer has been studied in different Reynolds numbers. Ferrofluid additives caused a tremendous improvement in the heat transfer of the fluid. The use of the alternating magnetic field also led to an increase in the heat transfer rate along with the spiral coil. Based on the results obtained in the constant volume fraction, if pure water is considered as the base fluid, then the ferrofluid with a constant magnetic field, the ferrofluid without a magnetic field, the ferrofluid with an alternating magnetic field of 5 Hz, and the ferrofluid with an alternating magnetic field of 50 Hz increased the heat transfer by 19%, 26%, 33%, and 43%, respectively.
