JEE Main 2025 · 7 Apr · Shift 2 · Bar Magnet and Magnetic Dipole

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): Magnetic monopoles do not exist.

Reason (R): Magnetic field lines are continuous and form closed loops.

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. (A)

    Both (A) and (R) are correct and (R) is the correct explanation of (A)

  2. (B)

    (A) is not correct but (R) is correct

  3. (C)

    (A) is correct but (R) is not correct

  4. (D)

    Both (A) and (R) are correct but (R) is not the correct explanation of (A)

Answer: (A)
