| ASSERTION: A linear solenoid carrying current is equivalent to a bar magnet. |
| REASON: The magnetic field lines of both are same. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
The magnetic lines of force due to current carrying straight solenoid are same as that of bar magnet (That's why at some places solenoid is used as temporary magnet).
