Summary The direction of a secondary magnetization component is found from the intersection point of converging remagnetization circles using a method based on the least‐squares fitting of great circles to points on a sphere. The technique may be applied to any problem that requires the best intersection point of convergent great circles and is thus useful in other fields besides palaeomagnetism, such as structural geology, plate tectonics and astronomy.
