Particles in this region experience the magnetic mirror effect.
Particles in this region experience the magnetic mirror effect. Highly energized protons from the decay of neutrons produced when cosmic rays collide with the Earth's atmosphere make up the inner part, while the outer part contains helium ions from the solar wind, and both parts are most intense over the equator and effectively absent above the poles. Discovered using data from the 1958 Explorer satellite, FTP, what is this doughnut-shaped belt of high energy particles trapped at high altitudes in the magnetic field of the Earth?
