Near point or least distinct vision - it is the distance from the eyes up to which eyes can have a clear vision is called least distinct vision. It is about 25cms for a normal healthy eye. THUS ADULT eyes can see the object from INFINITY to 25cm.

ong>Answer:

Magnetic hysteresis occurs when an external magnetic FIELD is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the MATERIAL has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely. To demagnetize it requires heat or a magnetic field in the opposite direction. This is the effect that provides the element of memory in a hard disk drive.

Theoretical model of magnetization m against magnetic field h. Starting at the origin, the upward curve is the initial magnetization curve. The downward curve after saturation, along with the lower return curve, form the main loop. The intercepts hc and mrs are the coercivity and saturation remanence.

The relationship between field strength H and magnetization M is not linear in such materials. If a magnet is demagnetized (H=M=0) and the relationship between H and M is plotted for increasing levels of field strength, M follows the initial magnetization curve. This curve increases rapidly at first and then approaches an asymptote called magnetic saturation. If the magnetic field is now reduced monotonically, M follows a different curve. At zero field strength, the magnetization is offset from the origin by an amount called the remanence. If the H-M relationship is plotted for all strengths of applied magnetic field the result is a hysteresis loop called the main loop. The WIDTH of the middle section along the H axis is twice the coercivity of the material.[1](Chapter 1)

A closer look at a magnetization curve generally reveals a series of small, random jumps in magnetization called Barkhausen jumps. This effect is due to crystallographic defects such as dislocations.[1](Chapter 15)

Magnetic hysteresis loops are not exclusive to materials with ferromagnetic ordering. Other magnetic orderings, such as spin glass ordering, also exhibit this PHENOMENON.[2]

ing's Left-Hand Rule is a simple and ACCURATE way to find the direction of force/motion of the conductor in an ELECTRIC motor when the magnetic field direction and the current direction are KNOWN. It was originally developed by John Ambrose Fleming, an English electrical engineer, in the late 19TH century.

The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month (about 29.53 DAYS) as the Moon's orbital POSITIONS around Earth and Earth around the Sun shift. The visible SIDE of the moon is variously sunlit, depending on the POSITION of the Moon in its orbit.
