That somehow reminded me of the "what if" article about stopping earth's rotation from one moment to another, except affecting the poles equally. It also has a taste of turning the landscape upside down, which sounds terrible. An interesting part about it would likely be what would be left of earth, since I guess earth's core material would be rather eager to be swallowed by the PBH, and we rely on a couple of properties of the core for the electromagnetic field. I'd imagine this would never be the same planet afterwards, at least not with the same gravitational attraction... or even comparable properties within the next geologic timescale.
