B (infinite straight conductor) = (μ0/4 π) (2I/a), where a is the distance of the observation point from 4 it a the conductor.

Q. The strength of the magnetic field around an infinite current carrying conductor is :

same every where

inversely proportional to the distance

inversely proportional to the square of the distance

directly proportional to the distance.

B (infinite straight conductor) = $\frac{μ _{0}}{4 π} \frac{2 I}{a}$ , where a is the distance of the observation point from 4 it a the conductor.
