A
The magnetic field is uniform in magnitude at every point on the circle.
B
The magnetic field varies linearly with the distance from the wire.
C
The magnetic field is zero at every point on the circle.
D
The magnetic field is strongest at the points closest to the wire.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the magnetic field at every point on a circle of radius r, with the wire along the axis, is uniform in magnitude.
