Question

Assertion: On freely suspending a current - carrying solenoid,
it comes to rest in N-S direction just like a bar magnet
Reason: One end of current carrying straight solenoid behaves
as a North pole and the other end as a South Pole

Answer 1

Both A and R are true , but R is The correct explanation of A.

Answer 2

The assertion and the reason are true and the reason is the correct explanation for the assertion.

• An electromagnet, like a bar magnet, is a solenoid. It applies generally to something like a bar magnet.
• A current-carrying freely hanging solenoid bears some resemblance to a bar magnet with fixed orientations at both ends.  
• The current-carrying linear electromagnet has one end that behaves as the North Pole and the other end that behaves as the South Pole.
• As an outcome, it lies in the same direction as a bar magnet in the North-South direction.
• As a consequence, both the claim and the reason are correct, with the reason serving as the proper justification for the statement.
