Select the option that is correct regarding the following two statements labelled Assertion (A) and Reason (R).
Assertion: The magnetic field lines do not form closed loops.
Reason: Magnetic field lines can never intersect.
-
A.
Assertion is true but reason is false.
-
B.
Both assertion and reason are true and reason is the correct explanation of assertion.
-
C.
Both assertion and reason are false.
-
D.
Assertion is false but reason is true.
Correct Answer:
D. Assertion is false but reason is true.
Explanation:
The assertion is false, but the reason is true. Magnetic field lines are continuous curves that always form closed loops, emerging from the north pole and entering the south pole outside a magnet, while moving from south to north inside it. Conversely, it is physically impossible for magnetic field lines to intersect because the magnetic field at any specific point can only have one unique direction; an intersection would imply that a compass needle could point in two different directions simultaneously.
