On the basis of satellite observations of the magnetic fields of earth, Jupiter, Mars, Mercury, and the moon as well as models of internal planetary structure, it is suggested that the dynamo fields of the planets are proportional to the product of the life-time of the field in a planet's core and the inertial force generated by the planet's precession. A simple proportion is established between the earth's dipole field and that of each of the other planets (and the moon) which takes into account the angle between rotational and precessional motions, the radii of planetary cores, and the intensity of the dipole fields at the core boundaries. It is shown that the constant of proportionality in this relationship is slightly different for Jupiter, Mars, Venus, and the moon. This slight variation is taken as evidence in favor of the precession mechanism for the dynamos of the earth, the moon, and the other planets.
