MAGNETIC FIELD DUE TO CURRENT CARRYING SOLENOID

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Magnetic field due to a solenoid having n number of turns per metre and carrying current I is `B=mu_(0)nI` which is independent of the length and area of cross section of the solenoid.
The magnetic field inside the solenoid is uniform.
