Non-Dipole Terms in the Magnetic Fields of Jupiter and the Earth

Abstract

MEASUREMENTS of the linear polarization of the radio radiation have been widely used to study the magnetic field of the planet Jupiter, and this method is believed to give the best estimate of the inclination and longitude of the magnetic axis1. When the position angle of polarization is plotted against central meridian longitude, l, the curve departs significantly from the simple sinusoidal form predicted for a dipole field, and previous workers1, 2, 3 have fitted harmonic series to the data, of the form
