hello! I am a highschooler and I've recently had this question in my exam: `Assertion (A): Magnetic field lines around a bar magnet never intersect each other.
Reason (R): Magnetic field produced by a bar magnet is a quantity that has both magnitude and direction.
A) Both assertion and reason are true, and the reason is the correct explanation for the assertion.
B) Both assertion and reason are true, but the reason is not the correct explanation for the assertion.
C) The assertion is true, but the reason is false.
