What are magnetic fields? (article) | Khan Academy

The magnetic field of the earth arises from moving iron in the earth's core. The poles of the earth's magnetic field are not necessarily aligned to the geographic poles. They are currently off by about 10 ∘ ^circ ∘ degree and over geological periods of time can flip. Currently the magnetic south pole is located near the geographic north pole.
