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.
MAGNET: A material that has the property, either natural or induced, of attracting iron or steel. MAGNETIC FIELD: The space around a magnet in which the magnetic force can be detected. 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.
The demagnetizing field, also called the stray field, is the magnetic field (H-field) generated by the magnetization in a magnet. The total magnetic field in a region containing magnets is the sum of the demagnetizing fields of the magnets and the magnetic field due to any free currents or displacement currents.he total magnetic field in a region containing magnets is the sum of the demagnetizing fields of the magnets and the magnetic field due to any free currents or displacement currents.
