Behavior of rising nitrogen (diamagnetic) bubbles in manganese chloride aqueous solution (paramagnet) is illustrated by an experiment and a numerical simulation. The bubbles obliquely rise toward the central axis under a high gradient magnetic field |grad(B
2)|=254 T
2/m(B=4.5T at the magnetic center). In this case, the outer region of the vessel has no bubbles above the oblique rising. On higher magnetic field, the rising velocity of the bubbles slows down and it stops under |grad(B
2)|=314T
2/m (B=5.0T at the magnetic center). Results of the numerical simulation agree with the experiment, and it gives a prediction of behavior of oxygen (paramagnetic) bubbles in the water (diamagnet).
