The Sun is in a solar minimum, the earths mag field is moving. Induction happens all of the time. I wonder if the movement of the fluid in the core is a result of the solar mag field. At least in part. Is the core ferrous? Wonder too if core has hysteresis.

There’s no connection that I’ve heard of between the sun’s magnetic field and the earth’s. That doesn’t mean there isn’t one.
