Calibrating a magnetometer can improve the accuracy of the magnetometer readings. All ferromagnetic materials will cause skew in the results of the measurements take by a magnetometer. This distortion falls into two categories, hard or soft iron distortion. We can also further fine tune our readings by including the magnetic declination of our current location.
