Stellar Magnetic Fields (Encyclopedia of Science)
Stellar magnetic fields are an assortment of powerful forces that can be observed at the surfaces of and surrounding stars like the Sun. Astronomers have yet to obtain a complete understanding of the magnetic fields of stars, but they continue to observe their activity in the hopes of understanding their effects on a star's interior makeup, atmosphere, rotation, and future evolution.
The mysterious magnetic field
A typical magnetuch as one commonly found on a refrigerators called a dipolar magnet. Dipolar refers to the two areas of the magnet from which it receives its power: opposing north and south poles. A star's magnetic field works in basically the same way, but it is much more complex. How stellar magnetic fields originate remains a mystery among astrophysicists. In space, there is no naturally occurring magnetic iron, yet astronomers know that magnetism does exist in space.
The most studied stellar magnetic field
The Sun, the only star our solar system, has show that it has a magnetic field that reaches all over its surface. Astronomers know that this magnetic field affects the rotation of the Sun and the movement of chemical elements around its surface. It has concentrated areas of magnetism called sunspots (dark areas on the Sun that produce magnetic storms).
