Abstract Optically induced rotation relies on dynamic optical forces acting microscopic particles via spatiotemporal light modulation, angular momentum transfer, or recoil forces. However, rotating macroscopic using fields with intensity, polarization, phase variations is challenging, especially underwater, due to the low torque of electromagnetic fields. This study demonstrates stable trapping and switchable light‐induced millimeter‐scale liquid marbles (LMs) in a uniform, time‐invariant DC magnetic field. These LMs, composed self‐assembled ferrofluid droplets encapsulated by superhydrophobic high photothermal conversion efficiency, float fluid surface are stably trapped controlled tension Light‐induced interactions within magneto‐optical field generate significant momentum, driving through Kelvin body force—resulting from thermo‐magnetic gradient—and enables optically magnetically coupled velocity tunable strength, viscosity, tension. Torques exceeding 170 nN·µm achieved 200 mW CW laser, modulating underwater transmission at 1–4 Hz. approach advances reversible generation communication fluidic systems. Additionally, ultrasonic waves modulate altering nonequilibrium force distribution LMs.
