The sun continuously produces billions of electrically charged particles, generated when hydrogen atoms are stripped apart in intense heat, due to fusion taking place in it. The negatively charged electrons are blown outward, being less constrained by gravity than the weightier, positively charged protons. The earth is surrounded by magnetic fields known as the magnetosphere, which deflects these…
