Again, not quite, but not unreasonable to think of it that way.
As a system, Earth's core is a molten iron mass. It spins, due to BOTH the spin of the mantle above it, and the original spin from transiting the Earth's solar plane, like a ball rolling on end around an oval plate. That molten iron core does two things, very well. One, creates a big enough gravity well to keep a certain amount of gases around it to form stable water molecules in solute. Second, that core spins in a unique way so as to create its own magnetic field, currently known as the North and South poles.
What's not as well known are two things. One, the current poles are suffering from some "drift" from the, what better way to describe them than the poles created by spin. (Axis plural is axes). Second, the poles have flipped every 700,000 years or so, and we're about 50,000 years overdue.
So, in summary, we know what causes the magnetic moment (spin induced poles) and that's the spinning core. What has never been known is what causes the flip. Is it the dissolution of the core, If, like with a pot of soup when you stop stirring, and then stir it the other way, type of dissolution? What's driving the core's "spoon"? Well it seems it may be the Sun after certain cycles of it's own, that physicists are just now starting to pull together since quiet period of 2010-202.
