I just wanted to know if there are instances of liquid materials that give rise to currents when they move in a region of constant magnetic field. I am drawing a parallel with the basic example of a “solid” loop moving in a magnetic field. Does the same phenomenon exist for liquids?

1A natural example is given by the Earth, where the liquid metal in the outer core goes through a magnetic field, which causes an electric current to flow within the liquid metal.
