It is proposed that the average geomagnetic field at the surface of the earth's core is the true dynamo-generated field, that equatorial symmetry is a fundamental consequence of the dynamo equations, and that the polar patches in the field are due to the dynamical influence of the inner core. The four main lobes of the average field are 120 deg apart; it is proposed that the flux from a missing third pair of lobes, which should appear symmetrically near the Greenwich meridian, has been redistributed by near-surface fluid flow to generate secular variation in the Atlantic hemisphere.
