Assertion : If some ferromagnetic substance is filled inside a solenoid, its coefficient of self induction `L` will increase.
Reason : By increasing the current in a coil, its coefficient of self induction `L` can be increased.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Ferromagnetic susbtance will attack more number of magnetic lines through it. So flux passing through it will increase. Hence, coefficient of self indsuctance will increase.
`L` depends on number of turns in the coil's radius of coil etc. If does not on the current passing through it.
