Magnetic Fields in the Formation of Sun-Like Stars
The scorching, swirling plasma and chaotic magnetic fields within the Sun, at the solar surface, and in the solar atmosphere create many different types of solar phenomena. Volume 16, article number 1, ( 2019 ) Cite this article. For the Earth, this could have been an external magnetic field. Here I shall focus on small-scale local structures near the surface of the . Here we describe the magnetic field as it threads its way from the bottom of the convection zone, where it is built up by the solar dynamo, to the solar surface, where it manifests itself in the form of sunspots and .The general magnetic field, producing the Sun's north and south magnetic poles, also reverses polarity at each cycle, the reversal typically occuring 3 years after sunspot minimum.
Earth's magnetic field
Spectra-spectroheliograph observations; D.In the standard model of isolated low-mass-star formation (3, 4), magnetized molecular clouds that are magnetically supported against gravitational collapse (or “subcritical”) are expected to slowly form dense molecular cores through ambipolar diffusion.
The magnetic field in the solar atmosphere
As a humorous saying attributed to the late Robert (Bob) Leighton, a prominent American astronomer, puts it: “If the sun didn’t have a magnetic field, then it would be as boring a star as most astronomers think it is.
Turbulent times for the Sun’s magnetic field
The bright active region right at the central area of the Sun clearly shows a concentration of field lines, as well as the small active region at the Sun’s right edge, but to a lesser extent.

(Editor’s Note: This story was originally issued August 2013. Earth is largely protected from the solar wind, a stream of energetic charged particles emanating from the sun, by its magnetic field. Here we build one of the simpler magnetic field models, called Potential Field Source Surface or PFSS, to construct how the magnetic 'lines of force' might look above the sun. Welcome to the Magnetic Sun You can navigate between the pages in order with the links at the top and bottom bars of each page, or jump to a particular section using the table of contents.Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged particles emitted by the Sun (the .
