JEE Main 2025 Physics question
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 :
Answer: (4)
Solution
Magnetic field lines form closed loops because monopoles do not exist; this directly explains the assertion.
