What creates the van Alan belts?

The Van Allen radiation belts are created by the interaction of solar wind and cosmic rays with Earth's magnetic field. Charged particles, primarily electrons and protons, become trapped in the magnetic field, leading to the formation of two main belts: the inner belt, composed mostly of high-energy protons, and the outer belt, which contains high-energy electrons. These belts extend from about 1,000 to 60,000 kilometers above Earth's surface and vary in intensity depending on solar activity.
