NEET Physics Ampere's Law MCQ Question
Which of the following combinations correctly describe the implications of Ampere's Law for a straight long wire and its magnetic field?
The magnetic field inside the wire is uniform, and the field outside decreases with distance.
The magnetic field is directly proportional to the total enclosed current and is directed tangentially to concentric loops.
The magnetic field inside the wire is inversely proportional to the distance from the center, regardless of current distribution.
Ampere's Law can be applied to any closed loop, regardless of the current's distribution within the surface it encloses.
Correct Answer
Detailed Explanation
Ampere's Law indicates that the magnetic field around a straight wire is directly proportional to the total current enclosed and is tangential to concentric circles surrounding the wire, as stated in the provided NCERT context.
