  The diamagnetism of ice particles of the rings can explain their separation
and the sharp edges of the rings. The existing gravitational theories of the
origin of rings can't explain these observed facts. Taking into account the
magnetic field of Saturn, all the particles of the rings acquire stability in
the horizontal and vertical directions. The force of diamagnetic expulsion of
inhomogeneous magnetic field inside the rings structure forms sharp edges and
separates the particles.
