Question
Assertion (A): Magnetic field lines never intersect each other.
Reason (R): If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
Options
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
Assertion (A) is true, but Reason (R) is false.
Assertion (A) is false, but Reason (R) is true.
Solution
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Explanation:
Magnetic field lines never intersect each other is true. This is because if they did intersect, it would imply that at the point of intersection, a compass needle would have to point in two different directions simultaneously, which is impossible. The reason provided explains this concept clearly and accurately, stating the impossibility of a compass needle pointing towards two directions at once due to the inherent nature of magnetic fields.
