Why does the magnetic north pole shift?

Answer:
It is believed that the earth's magnetic field is due to the dynamo effect within the nickel-iron core of the earth. The core is molten, a dense and highly compressed fluid. The physics must be well awesome. Anyway, the nature of a fluid is that it is has some mobility. And there is movement within the fluid core of the earth which will, therefore, cause the recorded shift in the location of the magnetic poles on the mantle of the earth.
Recall that the mantle of the earth, the tectonic plates and such, is actually "floating" on the liquid core.
I hope this helped you
