In the process of magnetization of a bar (a)The entire bulk of the bar gets magnetised (b)Only the surface of the bar gets magnetised (c)Only the ends of the bar get magnetised (d)Only some parts of the outer layers of the bar get magnetized
option A. In classical electromagnetism, magneti-zation or magnetic polari-zation is the vector area that expresses the density of everlasting or brought on magnetic dipole moments in a magnetic material. The starting place of the magnetic moments answerable for magnetization may be both microscopic electric powered currents on account of the movement of electrons in atoms, or the spin of the electrons or the nuclei. In the system of magnetization of a bar, the whole bulk of the bar receives magnetized. The magnetization of a cloth is finished with the aid of using electric powered current. By the system of magnetization, the fashioned portions increase North polarity on one stop or facet and South polarity on the alternative quit or aspect, in a completely brief duration of time.
