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.
The sun's magnetic field has two poles, like a bar magnet. The poles flip at the peak of the solar activity cycle, every 11 years. A solar wind composed of charged particles carries the magnetic field away from the sun’s surface and through the solar system. The sun is not a solid ball, but rather like a fluid.
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.
The twisting action also creates the solar dynamo, which allows it to constantly create magnetic field. The 11-year solar cycle of magnetic activity as the magnetic field of the Sun reverses itself around every 11 years (polar flip). The magnetic field of the Sun is not only surrounding the Sun, its field ranges beyond the Sun itself.
Magnetism is the key to understanding the Sun. Magnetic fields are produced in the Sun by the flow of electrically charged ions and electrons. Sunspots are places where very intense magnetic lines of force break through the Sun's surface. The sunspot cycle results from the recycling of magnetic fields by the flow of material in the interior.
The field causes activity at the surface of the sun, surging and ebbing in a regular cycle. At the peak of the cycle, the polarity of the field flips, during a time of maximum sunspot activity. The sun's magnetic field has two poles, like a bar magnet. The poles flip at the peak of the solar activity cycle, every 11 years.
