It is an interesting question whether or not magnetic fields have any influence on dissolved oxygen in living tissues and cells. This study focuses on the behavior of dissolved oxygen under strong magnetic fields of up to 8 T with the gradient of 50 T/m. We used a horizontal type of superconducting magnet. We placed a water chamber in the magnet's bore for 1 hour, then we took it out of the fields to measure the dissolved oxygen concentration. When oxygen gases were introduced into the distilled water to increase oxygen concentration more than 11 mg/l, we observed clear redistribution of dissolved oxygen concentration. The degree of the redistribution was dependent on the dissolved oxygen concentration at the initial condition. Redistribution of dissolved oxygen was not observed in an equilibratory state of oxygen pressure at the air atmosphere. We also observed that the increase and decrease In dissolved oxygen concentration during and after magnetic field exposures exponentially changed. The time constants for the increase and decrease were 17 min-18 min and 7 min-8 min, respectively
