A)
B)
C)
D)
Correct Answer: B
Solution :
The magnetic field due to a long wire carrying current Z, at a distance r is given by \[B=\frac{{{\mu }_{0}}}{2\pi }\frac{I}{r}\] \[\Rightarrow \] \[B\propto \frac{1}{r}\] Since B is inversely proportional to r, hence correct variation is shown by graph .You need to login to perform this action.
