The Explorer I satellite, launched by the United States on January 31, 1958, discovered the presence of the Van Allen radiation belts around Earth. The Van Allen radiation belts consist of charged particles trapped by Earth's magnetic field, and their discovery provided valuable insights into Earth's magnetosphere and the effects of space weather on our planet.
Objects such as compass needles, charged particles like electrons and protons, and solar wind are all influenced by Earth's magnetic field along its magnetic lines. These particles can be deflected or trapped by the field as they move through space.
The Earth has two main radiation belts called the Van Allen belts, named after their discoverer. These belts consist of charged particles, mainly electrons and protons, trapped by Earth's magnetic field. The belts are located in the region of space around the Earth where the magnetic field interacts with particles from the Sun.
The full motion is F=qvB where v and and B are vectors and the full motion is F= -qv.B + qvxb = qvB(-cos(angle) + vxBsin(angle)) there will be a scalar parallel to the field and the vector motion perpendicular to the field. This scalar field and motion is the real cause of so-called trapped particles. The vector motion is that of a mass spectrograph. The charged particle moves in a circle when perpendicular to the magnetic field.
The charged particles flowing through space around the Earth follow the lines of magnetic force, resulting in a higher concentration of these particles in two toroidal bands curving outward from pole to pole. The radiation belts are called the Van Allen Belts after scientist James Van Allen (1914-2006).
The Van Allen belts are composed of charged particles from the solar wind that became captured in the Earth's magnetic field. Deflection of charged particles
Charged particles from the sun become trapped in the Van Allen radiation belts due to the Earth's magnetic field. The magnetic field bends the charged particles' trajectories, causing them to spiral along the field lines and get trapped in the region around the Earth's magnetic poles.
The magnetosphere primarily attracts and deflects charged particles from the solar wind, such as protons and electrons. These particles are trapped and guided along the magnetic field lines of the Earth's magnetosphere, creating phenomena like auroras.
The ionosphere, a layer in the Earth's atmosphere, acts like a magnet by attracting charged particles such as electrons and ions. These charged particles are mainly attracted by the Earth's magnetic field, causing them to be trapped and move along the magnetic field lines in the ionosphere.
Objects such as compass needles, charged particles like electrons and protons, and solar wind are all influenced by Earth's magnetic field along its magnetic lines. These particles can be deflected or trapped by the field as they move through space.
The sun produces energetic and charged particles and blasts them in all directions (solar winds). These charged particles can get trapped when they are near the earth's magnetic field. With the grace of this magnetic field, we are all shielded from being irreversible harmed. See the picture in the related link for a visualization of how the magnetic field gets distorted by solar winds. ============================
Charged particles trapped in the Van Allen belts experience deflection due to Earth's magnetic field. They tend to spiral along the magnetic field lines, moving in a corkscrew pattern rather than directly from pole to pole. This deflection helps confine the particles within the belts.
Those are the Van Allen belts.
Once in orbit, the cosmic ray equipment of Explorer-I indicated a much lower cosmic ray count than had been anticipated. Dr. Van Allen theorized that the equipment may have been saturated by very strong caused by the existence of a belt of charged particles trapped in space by the earth's magnetic field. The existence of these Van Allen Belts, discovered by Explorer-I, was confirmed by Explorer-III, which was launched by a Jupiter-C on 26 March 1958.
Earth itself is largely protected from the solar wind by its magnetic field, which deflects most of the charged particles; however some of the charged particles are trapped in the Van Allen radiation belt. XxBaby Dee

No. it is created by the Earth's magnetic field, and particles trapped in it from the Solar wind.
