Optical tweezers was used to study the changing rule of the activity of the red blood cells in static magnetic field. Red blood cells irradiated by Gaussian laser beam were deformed. When the laser was cut off, the relative deformation value of blood cells was obtained, which was associated with the cells' activity. After comparing the decay process of cells activity between static red blood cells and red blood cells in magnetic field, the results showed the activity of the red blood cells increased by 0.20T magnetic field, meanwhile the cells' energy consumption increased. The death of cells has accelerated because of energy consumption. The research can provide valuable reference for the study of cells viability and dynamic analysis.
