Not only does a magnetic field set the direction of our compass needles, it also acts as a shield of sorts, … Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the Sun's corona and accelerating to a speed of 200 to 1000 kilometres per second. They carry with them a magnetic field, the interplanetary magnetic field (IMF). The solar wind exerts a pressure, and if it could reach Earth's atmosphere it w…
