In an L-R circuit, if an iron core is inserted inside the coil

A bulb and an air-cored coil are connected in series with a 20 V DC source. Now a soft-iron core is inserted inside the coil. During the time interval when iron core is being inserted

Assertion : In series L-C-R circuit, if a ferromagnetic rod is inserted inside an inductor, incr current in the circuit may ease or decrease. Reason : By doing so X_L will increase.

Assertion : In series L-C-R circuit, if a ferromagnetic rod is inserted inside an inductor, current in the circuit may increase or decrease. Reason : By doing so X_L will increase.

A coil and a bulb are connected in series with a dc source, a soft iron core is then inserted in the coil. Then

A coil and a bulb are connected in series with a dc source, a soft iron core is then ninserted in the coil. 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, then
