Question

The magnetic field produced near the current-carrying conductor is
Options
A stronger
Correct Answer
B weaker
C neutral
D none of above
Correct Answer

Option A is the correct answer.

Detailed Explanation

B = μ₀I/(2πr). The magnetic field is inversely proportional to distance from the conductor, so it is stronger near the conductor.

Hint

How does magnetic field strength vary with distance from a current-carrying wire?
