An experiment is carried out with two identical solenoids. A rod of soft iron is placed inside Solenoid 1, and an identical rod of steel is placed inside Solenoid 2.
Both solenoids are connected to a direct current (d.c.) power supply to magnetise the rods. The power supply is then switched off.
Which statement correctly describes the magnetic state of the rods after the current is switched off?
Both the soft iron rod and the steel rod remain magnetised.
Neither the soft iron rod nor the steel rod remains magnetised.
Only the soft iron rod remains magnetised.
Only the steel rod remains magnetised.
