What is a solar magnetic field?

The solar magnetic field couples the solar interior with the visible surface of the Sun and with its atmosphere. It is also responsible for all solar activity in its numerous manifestations. Thus, dynamic phenomena such as coronal mass ejections and flares are magnetically driven.

Is solar magnetic field a dipole?

The solar magnetic field is highly variable, which makes the solar wind and the magnetic field it carries with it into interplanetary space highly variable in space and in time. To a first approximation, the magnetic field near the visible solar surface can be regarded as a dipole like that of the earth.

Is solar magnetic field weaker than interplanetary magnetic field?

The dipole component of the solar magnetic field is much weaker than the interplanetary magnetic field. To compare them, the dipole magnetic field at the photosphere is roughly 50–400 μT. It then reduces with the distance in cube to approximately 0.1 nT at the Earth’s distance.

How does the magnetic field of the sun affect solar activity?

Also, the magnetic field of the Sun leads to many effects that are together named solar activity. This activity includes solar flares, prominences, sunspots, and difference in the solar winds that carry material through our Solar System. The effects of solar activity also can be seen from Earth.

What is a magnetic field in the solar atmosphere?

This publication provides an overview of magnetic fields in the solar atmosphere with the focus lying on the corona. The solar magnetic field couples the solar interior with the visible surface of the Sun and with its atmosphere. It is also responsible for all solar activity in its numerous manifestations.

How strong is the magnetic field of the Sun?

The solar magnetic field, generated by the turbulent, rapidly moving ionized gases in the Sun, is complex and subject to unexpected changes. Various types of measurements have shown that the strength of the Sun's magnetic field varies by a factor of a thousand or so in the vicinity of an active sunspot.
