Vedclass · Answer

(C) According to the Biot-Savart Law,the magnetic field $B$ produced by a long straight current-carrying wire at a distance $r$ is given by the formula $B = \frac{\mu_0 I}{2 \pi r}$.From this expression,it is clear that the magnetic field $B$ is inversely proportional to the distance $r$ from the wire $(B \propto \frac{1}{r})$.Therefore,as the distance from the wire increases,the magnetic field decreases in inverse proportion to the distance.

How does the magnetic field produced by a current-carrying straight wire vary with the distance from the wire?
