A
The magnetic field is uniform in magnitude at all points on the circle.
B
The magnetic field varies significantly across the circle.
C
The magnetic field is stronger near the wire and weaker further away.
D
The magnetic field direction is the same at all points on the circle.
Correct Answer
Option A
Detailed Explanation
