How solar wind can break through Earth's magnetic field

more »

Space is not empty. A wind of charged particles blows outwards from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the Earth’s magnetic field. Researchers now have an answer to one of the questions about how this actually occurs. When two areas with plasma (electrically charged gas) and magnetic fields with different orientations collide, the magnetic fields can be “clipped off” and “reconnected” so that the topology of the magnetic field is changed, they explain.
