Answer:
The magnetic particles in a soft iron nail will line up with the magnetic field when the current is switched on. ... Imagine we put a piece of soft iron in the middle of a coil of copper wire. When we switch on the current, the coil becomes an electromagnet. But also, the soft iron core becomes a magnet.
