Q1. [1] medium exam-ready
Assertion (A): The magnetic field produced by a current-carrying solenoid resembles the field of a bar magnet.
Reason (R): One end of the current-carrying solenoid acts as a north pole and the other end acts as a south pole.
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
(B) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(C) Assertion (A) is true, but Reason (R) is false.
(D) Assertion (A) is false, but Reason (R) is true.
- A Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- B Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
- C Assertion (A) is true, but Reason (R) is false.
- D Assertion (A) is false, but Reason (R) is true.

Model Answer
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Explanation
The textbook explicitly states that one end of a current-carrying solenoid behaves as a north pole and the other as a south pole — this directly causes the solenoid's field to resemble a bar magnet's field. So R correctly explains A, making option (A) correct.
