Question

Assertion: Magnetic field is not associated with a stationary charge. Reason: A magnetic field can be detected by means of its effect on a current carrying conductor.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

We know that magnetic field can only be produced by a moving charge and not by stationary charge. Hence, stationary charge can never produce magnetic field. The reason is also true.
