NEET Physics Ampere's Law MCQ Question
Which of the following statements about Ampere's Law is correct?
The integral of B . dl over a closed loop equals μ0 times the total current through the surface enclosed by the loop.
Ampere's Law applies only to straight conductors and cannot be used for coils or irregular shapes.
The current enclosed by an Amperian loop is always equal to the total current passing through the surface.
The direction of the magnetic field produced by a current is independent of the right-hand rule.
Correct Answer
Detailed Explanation
Ampere's Law states that the integral B . dl is equal to μ0 times the total current passing through the surface, as indicated in the NCERT context. The other statements reflect misconceptions about the applicability and characteristics of Ampere's Law.
