And guess what ? This started a german and soviet industry to build dynamo experiments with crazy machines using liquid metals. These were notably the Ponomarenko experiment and later the Riga experiments. At the same time, the science of flows interacting with electromagnetic fields, called magnetohydrodynamics, was taking off because liquid sodium was used to cool off nuclear power plants by injecting it in pipes, and the flow of that was in itself complicated. Soviet stuff, I tell you. The germans became quite good at it, too, below is an image of the design of the Karlsruhe dynamo. Not really the Sun, eh ?
