It is known that boiling heat transfer in nanofluids is affected by thermal resistance owing to the deposition of nanoparticles formed on the heating surface. The application of a magnetic field to magnetic nanofluids is considered to affect bubble behavior. However, the relationship between the magnetic field and the formation of the accumulation layer and the heat transfer rate is not fully understood. In this study, the effects of a magnetic field on the heat transfer and bubble behavior were investigated. Pool-boiling experiments were conducted in nanofluids containing Fe3O4 nanoparticles dispersed in pure water. It was demonstrated that the application of a magnetic field around the heating surface reduced the bubble diameter.
