Solar Dynamo
A dynamo is a mechanism for a star or planet to create magnetic field. One type of solar dynamo is turbulent convection, which researchers have simulated on a supercomputer. Like soup boiling on a stove, gas at the Sun's surface is heated from the bottom and cooled at the top. Since the gas conducts electricity, these motions produce magnetic fields.

*Please note: the SVS does not fulfill requests for copies of the tapes in our library. On some of our animation pages, there is a direct link to a video distribution service from which tapes, handled by the Public Affairs Office (PAO)/Goddard TV, including some of our animations may be ordered.
