This set of web pages provide an elementary introduction to the solar wind, starting with evidence from comet tails and continuing to Parker's theory of the Sun's corona and observations of the solar wind. A graphic exercise, suitable for the classroom, for tracing interplanetary magnetic field lines "dragged out" of the Sun by the solar wind is included. These pages are part of a larger site, "The Exploration of the Earth's Magnetosphere", that gives a non-mathematical introduction to the magentic properties of the sun and planets, space weather, and the motion of charged particles in magnetic fields. A Spanish translation is available.
