Answer:
Explanation:
THE BAR WILL MAGNETISED AS LONG AS THERE IS CURRENT IN THE CIRCUIT
Reason of this is:
Iron is highly ferromagnetic material. Hence, it allows maximum number of field lines to pass through it.
When current carrying solenoid is taken, it produces its own magnetic field inside and outside the solenoid.
When a soft iron bar/core is placed inside the solenoid, it magnetizes the iron bar thereby increasing the strength of the magnetic field inside the solenoid.
