If a bar magnet is placed in the close neighbourhood of a piece of unmagnetized soft iron, it is seen that this piece of soft iron will also behave as a magnet.
If iron fillings are bought to the free end of the soft iron, they would be immediately attracted and will stick to it.
If the bar magnet is taken away from the soft iron piece, the iron fillings will fall off indicating that the magnetism of the soft iron was for the duration of neighbourhood for which the bar magnet lies close to the soft iron.
The magnetization of the soft iron due to the presence of the permanent bar magnet is said to be the Induced Magnetism and the phenomenon of production of such magnetism is known as Magnetic Induction.
If the North-pole of the bar magnet is bought near the soft iron piece, a South-pole is induced on the end of the piece nearest the bar magnet, and if South-pole of the bar magnet is bought near the soft iron piece, a North-pole is induced on the nearer end.
It will be noticed that a similar pole is induced on the farther end of the soft iron, i.e., if a North-pole is bought near the soft iron the nearer end will be a South-pole and the farther end will be a North-pole.
