Boiling heat transfer, as an efficient heat transfer approach, that can absorb a large amount of latent heat during the vaporization, is especially suitable for heat transfer occasions with high heat flux demands. Experimental studies show that the surface tension coefficient of pure water can be reduced sharply (up to 25%) when it is magnetized by a magnetic field applied externally. In this paper, magnetized water (MW) was used as the work fluid to conduct boiling heat transfer experiments, to explore the influence of magnetization on the boiling characteristics of pure water. The electromagnetic device was used to magnetize water, and then the MW was used as the work-fluid of boiling heat transfer experiments, the bubble dynamic behavior of the MW boiling was captured by a video camera, and the characteristics and mechanism were analyzed. It was found that at the same conditions, the boiling of MW can produce more vapor bubbles of smaller size than the water without magnetization, which leads to a higher heat-transfer efficiency. This indicates that magnetization can enhance the boiling heat transfer of pure water. Furthermore, the thermal conditions required by magnetized water when the boiling is started are lower than the non-magnetized water boiling, which means the earlier start of nucleate pool boiling when using the MW.
