I suppose so … (as per the evidence in hand).
Looks like this study provides us with another data point about rotation, (or lack thereof), and volumes of molten iron in the core.

… or disrupt temporary emerging fields, resulting in an overall 'neutral' field (cancellation).
There's something about chaotic motion on these scales to learn from these measurements, I reckon.
