EXPLORING THE SUN’S MAGNETIC INFLUENCEApril 23, 2015

LT: I can model how certain forces are able to act on an object from a distance

PICTURE 1 EXPLANATION

Sun’s Magnetic Field Lines

Electric currents inside the sun generate a magnetic field that spreads throughout the solar system. 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. A solar wind composed of charged particles carries the magnetic field away from the sun’s surface and through the solar system.

• A solar flare is a magnetic storm on the Sun which appears to be a very bright spot and a gaseous surface eruption. Solar flares release huge amounts of high-energy particles and gases and are tremendously hot (from 3.6 million to 24 million °F). They are ejected thousands of miles from the surface of the Sun.

• Extra info… Sunspots occur where the sun's magnetic field loops up out of the solar surface and cool it slightly, making that section less bright. These disturbances in the sun's magnetic field make the sunspot about 2700°F (1500°C) cooler than the surrounding area.

PICTURE 3

• A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space. Prominences are held above the Sun's surface by strong magnetic fields and can last for many months. At some time in their existence, most prominences will erupt, spewing enormous amounts of solar material into space.

PICTURE 4

• Coronal mass ejections (abbreviated CME's) are huge, balloon-shaped plasma bursts that come from the Sun. As these bursts of solar wind rise above the Sun's corona, they move along the Sun's magnetic field lines and increase in temperature up to tens of millions of degrees. These bursts release up to 220 billion pounds (100 billion kg) of plasma. CME's can disrupt Earth's satellites. CME's usually happen independently, but are sometimes associated with solar flares.

PICTURE 5

• The solar wind is a continuous stream of ions (electrically charged particles) that are given off by magnetic anomalies on the Sun. The solar wind is emitted where the Sun's magnetic field loops out into space instead of looping back into the Sun.
