The electrical conductivity of the molten plasma of the Earth's core should be able to damp the current magnetic field in only thousands of years. Yet our five billion year old Earth clearly causes magnets to point north. The mystery is still being studied but recently events (Global warming) related to motions in the Earth's liquid outer core. Specifically, as portions of the outer core cool and fall inward, oceans of the liquid iron-rich magma rise outward, forced into a helical motion by the spin of the Earth. This motion, many geologists now believe, regenerates Earth's magnetism. Therefore the answer is yes. If the climate changes enough the poles could move.

No, the fact that the earths iron core is highly propulsive and has an abundant source of electric currents running through it suggests that the reverse of its polarity is irrelevant in some way. But because it has happened before, It can happen again and it would be in a hundred years or so.

inside the iron core NO
around the iron core YES
the nickel surrounding it is the trick and it has happened loads of times, i think we are about to experience one soon btw

This supposedly has happened a couple of times in the history of the earth.

It happens every 10,000 years or so and we are overdue for it now.
