Supplementary Figure 1: Experimental setup for the LED lamps used in the inverted microscope. A. LED lamp. B. Microscope lamp position and condenser lens. C. Microscope stage and the pair of coils generating the constant magnetic field.

Supplementary Figure 2: Experimental setup in the inverted microscope to generate the magnetic and RF fields. A: square coil connected to a function generator providing a sine voltage in the proper frequency. B: pair of coils connected to a power supply providing a constant voltage to generate the magnetic field. RF: the white arrow represents the RF field direction relative to the surface of the microscope slide. MF: the black arrow represents the magnetic field direction relative to the surface of the microscope slide. Both fields, constant and RF, were perpendicular.

Video Captions.

Video 1: The effect of blue light (469 nm) on the movement of CMms. The conditions are the same as that for Table II: B0 = 0.4 mT and light power of 121 μW. The microorganisms are directed to the drop border because the local magnetic field corresponds to the North magnetic pole. The inversion of the magnetic field direction stimulates the movement of CMms away from the drop border. The velocity is measured during that magnetotactically stimulated movement.

Video 2: The effect of blue light (469 nm) on the movement of CMms in the presence of RF fields. The conditions are the same as that for Table II: B0 = 0.4 mT, fRF = 11.5 MHz and light power of 121 μW. The microorganisms are directed to the drop border because the local magnetic field corresponds to the North magnetic pole. The inversion of the magnetic field direction stimulates the movement of CMms away from the drop border. The velocity is measured during that magnetotactically stimulated movement.

Video 3: The effect of green light (517 nm) on the movement of CMms. The conditions are the same as that for Table II: B0 = 0.4 mT and light power of 121 μW. The microorganisms are directed to the drop border because the local magnetic field corresponds to the North magnetic pole. The inversion of the magnetic field direction stimulates the movement of CMms away from the drop border. The velocity is measured during that magnetotactically stimulated movement.

Video 4: The effect of blue light (517 nm) on the movement of CMms in the presence of RF fields. The conditions are the same as that for Table II: B0 = 0.4 mT, fRF = 11.5 MHz and light power of 121 μW. The microorganisms are directed to the drop border because the local magnetic field corresponds to the North magnetic pole. The inversion of the magnetic field direction stimulates the movement of CMms away from the drop border. The velocity is measured during that magnetotactically stimulated movement.

Video 5: The effect of red light (628 nm) on the movement of CMms. The conditions are the same as that for Table II: B0 = 0.4 mT and light power of 121 μW. The microorganisms are directed to the drop border because the local magnetic field corresponds to the North magnetic pole. The inversion of the magnetic field direction stimulates the movement of CMms away from the drop border. The velocity is measured during that magnetotactically stimulated movement.

Video 6: The effect of blue light (628 nm) on the movement of CMms in the presence of RF fields. The conditions are the same as that for Table II: B0 = 0.4 mT, fRF = 11.5 MHz and light power of 121 μW. The microorganisms are directed to the drop border because the local magnetic field corresponds to the North magnetic pole.
