Q. In the figure shown the magnetic induction at the centre of the arc due to the current in portion AB will be
A) $\frac{\mu_{0}i}{r}$
B) $\frac{\mu_{0}i}{2r}$
C) $\frac{\mu_{0}i}{4r}$
D) Zero
Explanation
(d) The magnetic induction at $O$ due to the current in portion $AB$ will be zero because $O$ lies on $AB$ when extended
