Question:

Magnetic field at large distances on the axis of a current carrying circular loop depends on distance from the centre as

Options:

directly proportional to distance

inversely proportional to the distance

inversely proportional to the square of distance

inversely proportional to the cube of distance

Correct Answer:

inversely proportional to the cube of distance

Explanation:

The correct answer is Option (4) → inversely proportional to the cube of distance

Magnetic field at large distances on the axis of a current carrying circular loop depends on distance from the centre as inversely proportional to the cube of distance.
