Assertion (A): A current carrying solenoid when suspended freely sets itself in the north-south direction just like a bar magnet.
Reason (R): The end of the solenoid where the direction of current is anti-clockwise behaves as a north pole and the end where the direction of the current is clockwise behaves as a south pole.
- Both A and R are true and R is the correct explanation of A
- Both A and R are true and R is not the correct explanation of A
- assertion is false but reason is true
- assertion is true but reason is false.
Both A and R are true and R is not the correct explanation of A.
Explanation
Assertion (A) is true. A current-carrying solenoid behaves like a magnet and aligns itself in the north-south direction when freely suspended, similar to a bar magnet. This behavior is due to the magnetic field produced by the current flowing through the solenoid.
Reason (R) is true. The direction of the magnetic field inside a solenoid depends on the direction of the current. The end of the solenoid where the current circulates anti-clockwise acts as a north pole, while the end where the current circulates clockwise acts as a south pole.
But here reason does not justify its assertion.
