Spinning a Liquid Wheel and Driving Surface Thermomagnetic Convection with Light (Adv. Mater. 7/2024)

Tesla Thermo‐Magnetic Motor A laser beam impinging on a ferrofluid droplet can generate not only a double‐eye vortex of surface thermomagnetic convection but also propel the droplet to spin like a Tesla thermomagnetic engine, which, in turn, causes two other droplets to spin in opposite directions t...

Description
Summary:Tesla Thermo‐Magnetic Motor A laser beam impinging on a ferrofluid droplet can generate not only a double‐eye vortex of surface thermomagnetic convection but also propel the droplet to spin like a Tesla thermomagnetic engine, which, in turn, causes two other droplets to spin in opposite directions through a thermal bridge.
