  Here we demonstrate how Saturn could create its rings by itself, with the
additional action of its axisymmetric magnetic field once appeared. A new
mechanism for the origin of Saturn's rings is proposed for the first time. It
includes the appearance of an additional third force - the force of diamagnetic
expulsion of a diamagnetic ice particle after the emergence of the magnetic
field of Saturn and the mechanism of magnetic anisotropic accretion. This force
is acting together with force of gravity and centrifugal one on the particles
within protoplanetary cloud. After appearance of the force of diamagnetic
expulsion of ice particles, all their chaotic orbits start shifting to the
magnetic equator plane, where the minimum of magnetic energy of the particles
is observed. Every particle on the magnetic equator comes to a stable position,
and it prevents its horizontal and vertical shift. The particles are trapped
within three-dimensional magnetic well.
