ANSWER____(. ❛ ᴗ ❛.)
The soft iron inside the coil makes the magnetic field stronger because it becomes a magnet itself when the current is flowing. Soft Iron is used because it loses its magnetism as soon as the current stops flowing. Soft iron is said to form a temporary magnet. In this way, the electromagnet can be switched on and off by turning the electricity on and off.
