Options:

Answer:

Solution:

The strength of magnetic field around a straight current carrying wire is given by

$B = \frac{μ_{0}}{2 π} . \frac{I}{r}$

$∴ B \propto \frac{1}{r}$

Therefore, magnetic field due to a straight current carrying wire is inversely proportional to the distance from the wire.
