Fig6_9 Far Magnetic Fields

Fig. 6.9 . In the low solar corona, strong magnetic fields are tied to the Sun at both ends, trapping hot, dense electrified gas within magnetized loops. Far from the Sun, the magnetic fields are too weak to constrain the outward pressure of the hot gas, and the loops are opened up, allowing electrically charged particles to escape. They form the solar wind that carries the magnetic fields away from the Sun. (Courtesy of Newton Magazine, the Kyoikusha Company.)
