Explanation:
When the iron rod is inserted, the magnetic field inside the solenoid is increased. This increases the inductance of the solenoid. ... Consequently, a large fraction of the applied AC voltage appears across the solenoid. As a result of this, there is a less voltage across the bulb and the brightness of the bulb decreases.
