Solar Magnetism
The Sun appears to shine at a constant rate. However, its magnetic field is actually constantly changing, and this affects energy output. These variations cause effects that extend throughout the solar system. This video segment, adapted from a NOVA television broadcast, introduces viewers to some of the effects of the sun's magnetic field, such as sunspots, auroras, and variations in the sunspot cycle which may affect Earth's climate. The segment is two minutes fifty seconds in length.
