Shape deformation of the gas-liquid interface of liquid oxygen condensed in a glass tube in high magnetic fields is investigated by taking photos. It is found that there is a simple relationship between the deformation of the gas-liquid interface and the square of the applied magnetic field in a range of 0–∼2 T, and that the shape of the interface changes tremendously from an ellipsoid into a sharp-pointed form with an increase in the field strength, breaking the linear relation. Regarding these experimental results, we carry out a discussion based on the phenomenological theory of a magnetic fluid.
