In the process of magnetisation of a bar
The entire bulk of the bar gets magnetised
Only the surface of the bar gets magnetised
Only the ends of the bar get magnetised
Only some parts of the outer layers of the bar get magnetised
The entire bulk of the bar gets magnetised
In classical electromagnetism, magneti-zation or magnetic polari-zation is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. The origin of the magnetic moments responsible for magnetization can be either microscopic electric currents resulting from the motion of electrons in atoms, or the spin of the electrons or the nuclei. In the process of magnetization of a bar, the entire bulk of the bar gets magnetized. The magnetization of a material is done by electric current. By the process of magnetization, the formed pieces develop North polarity on one end or side and South polarity on the other end or side, in a very short period of time.
