Magnetic Field of Straight Wires

The strength of magnetic field at a perpendicular distance ' $x$ ' near a long straight conductor carrying current ' I ' is ' B '. The magnetic field at a distance $\frac{x}{3}$ from straight conductor will be

Show answer and solution

Answer: (b)

$B \propto \dfrac{1}{x}$ for a long straight conductor.
At $\dfrac{x}{3}$ : $B' = 3B$
So the answer is (b) 3B.
