Solar Magnetic Activity

Solar magnetic activity refers to the dynamic phenomena caused by the Sun’s magnetic field, which is constantly moving and changing inside the Sun. This activity creates features like sunspots—dark areas with intense magnetic fields—and solar flares, which are bursts of energy. It also drives the solar wind, a stream of charged particles flowing outward. These processes can influence space weather, affecting satellites, power grids, and communications on Earth. Solar magnetic activity follows an approximately 11-year cycle, with periods of higher and lower activity, shaping the Sun’s visible features and impacting our planet’s environment.
