The coil system is powered by a signal generator and power amplifier to generate the sinusoidal field, and the amplitude and frequency of the field can be varied.

The rotor motion was observed and recorded using a high-speed camera at 240 fps. The associated fluid flow field was tracked using open source PIV Software (PIVLab38). The PIV images were created by placing tracer particles on the surface of the fluid, and the velocities of the particles were tracked and averaged over 3000 frames of the recording. The experimental setup was designed and constructed for the project by Platform Kinetcs Ltd (https://www.platformkinetics.com/).

Table Table11 shows the experimental values that we use in our experiments.
