NEET Physics Ampere's Law MCQ Question
Which of the following statements about Ampere's Law is correct?
The integral form of 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 bounded by the loop.
Ampere's Law can only be applied to infinite straight wires and not to any other configurations.
The right-hand rule is not applicable when determining the direction of the magnetic field in relation to the current in Ampere's Law.
The expression B . dl equals μ₀ multiplied by the current enclosed by any Amperian loop, regardless of the loop's shape.
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 bounded by the loop, as mentioned in the NCERT context. Options B, C, and D misinterpret the conditions and applications of Ampere's Law.
