I think it’s the same but different rates of propagation. It’s about potential force and gradient descent in the end. It’s also interchangeable. The water moves a physical object which induces a moving magnetic field which induces current in a conductor which moves through the circuit and can induce a magnetic field in a conductor which can move a magnetic which can move water.
