In this study, we aimed to examine the effects of a 2 mT strength static magnetic field, which is generated by placing a permanent magnet in water for 1 h, on the physical properties of magnetized water, such as its viscosity, conductivity, and pH value. The growth and yield of Phaseolus vulgaris irrigated with tap water and magnetized water were also examined and compared. We further evaluated its morphological characteristics, such as plant height, number of pods per plant, number ABSTRACT of seeds per pod, and fresh and dry weight of seeds, and physiological parameters (i.e., chlorophyll content, total sugar content, some elements, and crude protein concentration). As per our findings, the measured parameters of plants irrigated with magnetized water exhibited remarkable increases compared to those irrigated with tap water, in addition to increased seed production at harvest and changes in the concentration of elements. Despite the weak strength of the magnetic field, the pH value increased by 11.6%, viscosity by 10%, and conductivity by 10%.
