Directions : In the following questions, A statement of Assertion (A)...
On introducing soft iron core, the bulb will glow dimmer. This is because on introducing soft iron core in the solenoid, its inductance L increases, the inductive reactance, XL=ωL increases and hence the current through the bulb decreases.

Directions : In the following questions, A statement of Assertion (A)...
Assertion: A bulb connected in series with a solenoid is connected to an AC source. If a soft iron core is introduced in the solenoid, the bulb will glow brighter.
Reason: On introducing a soft iron core in the solenoid, the inductance increases.
The correct answer is option 'B' - If the assertion is false but the reason is true.
Explanation:
Assertion: A bulb connected in series with a solenoid is connected to an AC source. If a soft iron core is introduced in the solenoid, the bulb will glow brighter.
When a solenoid is connected to an AC source, an alternating current flows through it, creating a magnetic field. This magnetic field induces an alternating current in the soft iron core when it is introduced into the solenoid. The alternating current in the soft iron core magnetizes it, leading to the formation of temporary magnetic poles. These magnetic poles enhance the magnetic field produced by the solenoid.
Reason: On introducing a soft iron core in the solenoid, the inductance increases.
The inductance of a solenoid is directly proportional to the number of turns of wire and the magnetic permeability of the core material. When a soft iron core is introduced into the solenoid, the magnetic permeability of the core material increases significantly compared to air or vacuum. This increase in magnetic permeability results in a higher inductance value for the solenoid.
Now, let's evaluate the given assertion and reason:
- The assertion states that the bulb connected in series with the solenoid will glow brighter when a soft iron core is introduced. This is because the magnetic field produced by the solenoid is enhanced by the presence of the soft iron core, resulting in a stronger electromagnetic induction. As a result, the bulb receives a higher voltage and glows brighter.
- The reason states that on introducing a soft iron core in the solenoid, the inductance increases. This is correct as the inductance of a solenoid does increase when a soft iron core is introduced due to the higher magnetic permeability of the core material.
Hence, the assertion is true, but the reason alone does not provide a correct explanation for the assertion. The reason only explains why the inductance increases, but it does not directly explain why the bulb connected in series with the solenoid will glow brighter. Therefore, the correct answer is option 'B' - If the assertion is false but the reason is true.
