The Earth's magnetic field is influenced by the interplanetary magnetic field and charged particles in space that are mainly produced by the Sun. During active solar conditions ( solar storms ) more charged particles are released into space, affecting the normal conditions of the Earth's natural electromagnetic environment. This, in turn, affects normal operation of space and ground technologies, such as communication and navigation satellites, power grids and pipelines.
