Figure S1. A PG plate hanging on a string, aligning parallel to magnetic field lines in a uniform magnetic field, Video S1. A graphite plate hanging from a rubber string enters a uniform magnetic field, aligning parallel to the magnetic field lines, and then exits the magnetic field, unaligning. The video is at 1x speed, Video S2. A graphite plate hanging from a rubber string is between two far apart magnetics, randomly aligned. The magnets then come closer to each other, creating a uniform magnetic field, and then the plate aligns parallel to the magnetic field lines. The video is at 4x speed, Figure S2. Photo of a 5×5 mm PG plate with a mirror glued onto one side, Figure S3. COMSOL figure geometry that is used for simulated experiments, Figure S4. Comparison of theoretical and experimental data on flux density at different heights Z, Figure S5. Response time variations plotted against laser power with data points acquired at R = 2.5 cm, Table S1. Response times from the plots in Figure S2, Video S3. A bare pyrolytic graphite plate is shown tilting under 532 nm laser irradiation and recovering to its original tilt angle after the laser is blocked. The video is at 1x speed. The same dynamics were observed for a plate with a coverslip glued to the upper surface (not shown in this video), which was used for precise determination of the tilt angle, Figure S6. Plot of torque against tilt angle for various magnetic susceptibility values
