Q. The strength of the magnetic field around an infinite current carrying conductor is :
A
same every where
14%
B
inversely proportional to the distance
14%
C
inversely proportional to the square of the distance
43%
D
directly proportional to the distance.
29%
Solution:
B (infinite straight conductor) = $\frac{\mu_0}{4 \,\pi} \frac{2I}{a}$, where a is the distance of the observation point from 4 it a the conductor.
