Algebar and Elgebar are seen in poetry for this star, but it universally is known as Rigel, from Rijl Jauzah al Yusra, the Left Leg of the Jauzah (Jauzah was the Arabic title for Orion), by which extended title the Arabians knew it after the word Jauzah had become a personal title; the modern name first appearing in the Alfonsine Tables of 1521.

MAGNETIC FLUX: The total magnetic induction across or through a specified area. MAGNETIC INDUCTION, B: The production of magnetic properties in a magnetizable substance when placed in a magnetic field.
Magnetosphere= the region of space around a planet in which the motion of charged particles is dominated by the planet's magnetic field . Without the magnetosphere, auroras would be more common and widespread because the solar wind would be striking the Earth constantly, although only on the daylight side.
