A scientist studying earths magnetic field found that at hot springs Arkansas her compass pointed 5 degrees east of true north. In Durango, Colorado she took another reading and found that her compass pointed 14 degrees east of true north.
This is because the magnetic north pole and the geographic north pole are not in the same location. The magnet in the compass is attracted to the magnetic north pole not to the geographic north pole. There are different readings because she is also in two different places.
