Question

Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): A magnetic monopole does not exist.
Reason (R): Magnetic lines are continuous and form closed loops.
In the light of the above statements, choose the correct answer from the options below:

• A. (A) is false but (R) is true
• B. (A) is true but (R) is false
• C. Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
• D. Both (A) and (R) are true and (R) is the correct explanation of (A)

Hint:

When dealing with assertion and reason questions, remember that the reason may be true even if it doesn't explain the assertion. Always verify the logical connection between the two statements.

Answer 1

The Correct Option is C

- Assertion (A): The non-existence of a magnetic monopole is asserted. This is accurate; no experimental evidence supports the existence of solitary magnetic poles. Magnetic fields inherently possess both north and south poles, and the magnetic monopole remains a theoretical construct.
- Reason (R): Magnetic field lines are described as continuous and forming closed loops. This statement is also accurate. Magnetic field lines are indeed continuous and always form closed loops, whether contained within the magnet or extending outward.
However, the explanation provided in (R) does not directly justify the assertion in (A). The continuity and closed-loop nature of magnetic lines do not preclude the possibility of magnetic monopoles.
Consequently, both statements (A) and (R) are factually correct, but (R) does not serve as an explanation for (A). Therefore, the correct designation is (3).
