Abstract <p>Cassini’s measurements suggest that ice bodies of Saturn’s visible dense rings have diamagnetic properties. The James Webb space telescope (JWST) confirmed the existence of water around forming planets and showed that the magnetic field plays an important role in the formation of planets. It follows that Saturn’s visible dense rings could arise from the ice bodies of a protoplanetary cloud with the radius of the Roche limit under the combined action of a diamagnetic expulsion produced by Saturn’s magnetic field together with Saturn’s gravitational and centrifugal forces. As a result, Kepler’s orbits of the ice bodies of the protoplanetary cloud move into the plane of Saturn’s equator and form a highly compressed stable system of the visible dense rings with separate individual ice bodies. Due to magnetization by Saturn’s magnetic field, the magnetic moments of ice bodies align in the same orientation, causing them to repel and separate. Ice bodies are also attracted to each other due to their own gravity. At the balance of all the forces, the ice bodies remain at an equilibrium distance from each other. This provides an important proof for J.C.&#xa0;Maxwell’s discovery made in 1856 that Saturn’s visible dense rings are not continuous, but are composed of individual bodies. The presented theory offers an explanation for the origin of Saturn’s visible dense rings and their structure as observed by the Cassini probe in 2004–2017. It can also improve purely gravitational models of the origin of Saturn’s visible dense rings, which can show only how additional ice could penetrate the visible dense rings, but cannot convincingly explain their origin and structure.</p>
