  The magnetization relationships for magnetically uniform spherical particles
of the Saturn rings are derived. The problem of a solitary magnetized sphere
and spherical particle among identical particles scattered in a disk-like
structure is solved. The differential equations of motion of particles in the
gravitational and magnetic field are derived. Special cases of these equations
are solved exactly, and their solutions suggest that the superposition of the
gravitational attraction and repulsion by a magnetic field of the iced
particles which possess diamagnetism can account for the stability of Saturn
rings.
