A solenoid is connedted to a source of constant EMF for a long time. A sof iron piece is inserted into it. Then :

A solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, will the current increase or decrease? Explain.

Assertion: A bulb connected in series with a solenoid is connected to AC source. If a soft iron core is introduced in the solenoid, the bulb will glow brighter. Reason: On introducing soft iron core in the solenoid, the inductance increases.
