The magnetic poles or dip poles are computed from all the Gauss coefficients using an iterative method. Magnetic poles derived in this fashion are geographically closer to the experimentally observed poles. Based on the current WMM, the 2020 location of the North Magnetic Pole is 86.50°N and 164.04°E and the South Magnetic Pole is 64.07°S and 135.88°E.
