There is only one location where this occurs, near the Geographic North Pole and the Geomagnetic North Pole. Since the Earth's magnetic field is not exactly symmetrical, the North and South Magnetic Poles are not antipodal, meaning that a straight line drawn from one to the other does not pass through...
