The dynamics of the electrostatic disruption products of fragile interplanetary dust aggregates which are initially electrically charged on entering the Jovian plasmasphere is considered. The detailed orbits of these charged particles, which are shown to be confined to the equatorial plane, are computed. It is found that the fragments with radii typically about 1 micron are magnetogravitationally trapped within the plasmasphere due to the velocity-induced oscillation of their surface potentials. It is suggested that the distribution of micrometeroid dust within the Jovian magnetosphere, observed by Pioneer 10 and the recent Voyager, is a result of the magnetogravitational trapping and subsequent orbital evolution of these charged dust particles.
