Identify the substance that is easy to magnetize and demagnetize?

Solution
The correct option is C Soft Iron
Soft iron makes stronger magnetic field because it becomes a magnet itself when the current is flowing. Also, soft iron loses its magnetism as soon as the current stops flowing. Thus, soft iron easily magnetizes and demagnetizes. Hence, it is used as a core in making electromagnets.
