NEET Physics Ampere's Law MCQ Question
Imagine a circular loop with a magnetic field B tangent to it at every point. If the loop encloses a current I, which statement correctly describes the application of Ampere's Law to this scenario?
The integral of B around the loop equals μ₀ times the current I enclosed.
The integral of B around the loop equals zero if the current is uniform.
The integral of B around the loop is independent of the current enclosed.
The integral of B around the loop is proportional to the square of the current I enclosed.
Correct Answer
Detailed Explanation
Ampere's Law states that the line integral of the magnetic field B around a closed loop is equal to μ₀ times the total current I passing through the surface enclosed by the loop.
